What does b1 and b2 mean in math?Space and Astronomy
What does b2 mean in math?
b1, b2 are the lengths of each base. h is the altitude (height) Recall that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases.
How do you solve b1 and b2?
Video quote: So dividing by 1/2 the same thing as multiplying by the reciprocal. So. I have B 1 plus B 2 equals 2a over H. And I want to solve for B 1 so I just subtract B subscript.
What is the formula for b1 of a trapezoid?
The area of a trapezoid is A= (1/2) h (b1 + b2) , where h=height of the trapezoid, b1= 1st base, and b2= second base.
What is a2 b2 in algebra?
a2 – b2 = (a – b)(a + b)
How do you calculate b2?
Video quote: Answer using PEMDAS we simplify and we get 12 squared is 144 x squared is x squared of course and 13 squared is 169.
Is a 2 B 2 C 2 only for right triangles?
If a2 + b2 = c2, then the triangle is right. If a2 + b2 > c2, then the triangle is acute. If a2 + b2 < c2, then the triangle is obtuse.
How do you do the Pythagoras converse?
Video quote: That if the sum of the squares of two sides of a triangle is equal to the square of a third side or a squared plus B squared equals C squared then the triangle is a right triangle.
How do you find a hypotenuse?
Video quote: Right you can label however you like to just know that it's leg squared plus leg squared is going to equal your hypotenuse squared. So two square root of two squared.
How do you do inverse Pythagoras?
Video quote: So c times h. And now we have this equation. Right here we can multiply both sides by two so that one half will be gone and we'll just look at this as a b equals c h.
How do you use Pythagorean Theorem when B is missing?
Video quote: We can use the Pythagorean theorem a squared plus B squared equals C squared to solve for the missing sides and in this problem we have to solve for B.
How do you find B in the Pythagorean Theorem?
Solve for the Length of Side b
The length of side b is the square root of the squared hypotenuse minus the square of side a.
How do you find B in A2 B2 C2?
Video quote: Cool right triangle let's make a theorem that's exactly how that happened hashtag who Pythagoras okay fairy theorem is a squared plus B squared equals C squared.
How do you find A and B with only C?
Video quote: So referencing angle a notice that side B is the adjacent side and side C is the hypotenuse. And since the cosine function value involves the adjacent side and hypotenuse of a right triangle.
How does a2 plus b2 equal c2?
The Pythagorean Theorem describes the relationship among the three sides of a right triangle. In any right triangle, the sum of the areas of the squares formed on the legs of the triangle equals the area of the square formed on the hypotenuse: a2 + b2 = c2.
Is Pythagorean Theorem algebra?
Pythagorean theorem is super important for math. You will probably learn about it for the first time in Algebra, but you will literally use it in Algebra, Geometry, Trigonometry, Precalculus, Calculus, and beyond!

What do you mean by hypotenuse?
Definition of hypotenuse
1 : the side of a right-angled triangle that is opposite the right angle. 2 : the length of a hypotenuse.
Did Pythagoras came to India?
Analyzing the life of Pythagoras, he was a traveler. He traveled so many countries to gain knowledge. In that course he also visited India.
Who invented zero?
About 773 AD the mathematician Mohammed ibn-Musa al-Khowarizmi was the first to work on equations that were equal to zero (now known as algebra), though he called it ‘sifr’. By the ninth century the zero was part of the Arabic numeral system in a similar shape to the present day oval we now use.
Who was the first mathematician in the world?
Thales of Miletus
One of the earliest known mathematicians were Thales of Miletus (c. 624–c. 546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed.
Who Discovered value of pi?
Archimedes of Syracuse
The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
Why is 3.14 called pi?
It was not until the 18th century — about two millennia after the significance of the number 3.14 was first calculated by Archimedes — that the name “pi” was first used to denote the number. In other words, the Greek letter used to represent the idea was not actually picked by the Ancient Greeks who discovered it.
Why is pi important?
In basic mathematics, pi is used to find the area and circumference of a circle. Pi can be used to find an area by multiplying the radius of the circle squared times pi.
What are 5 facts about pi?
Here are seven more:
- Pi is all encompassing.
- Pi is ancient.
- We’ve used computers to calculate pi to more than 22 trillion digits.
- Humans have memorized vast stretches of pi.
- Pi has a bit part in many books and movies.
- Even rocket scientists only need a bit more than a dozen decimal places.
How do you explain pi to a child?
Video quote: It's very important in the study of circles pi stands for the ratio of a circles circumference to its diameter. The diameter is the distance across the circle.
Is pi an infinite?
No matter how big your circle, the ratio of circumference to diameter is the value of Pi. Pi is an irrational number—you can’t write it down as a non-infinite decimal.
