Question

Say you have a right triangle with side a = 40 and side c = 58. What is the length of side b

Answer 1

40^2 + x^2 = 58^2

x=42 ---> length of side b

Answer 2

So here you use pythagorean theorem
a^2 + b^2 = c^2
you are given a= 40 and c= 58
b^2 = c^2 - a^2
plug the numbers in and you will get your answer :)

Answer 3

does ^ mean squared?

Answer 4

yes

Answer 5

ok

Answer 6

\[a^{2} + b ^{2} = c ^{2} \]

Answer 7

but i dont know what B is

Answer 8

but you know a and c
so there is only 1 unknown variable

so rearrange the formula

to b^2 = c^2 - a^2

Answer 9

\[b= \sqrt{c ^{2}-a^{2}}\]

Answer 10

to square a number u times it by itself or times 2?

Answer 11

times it by itself

Answer 12

3^2 = 9 < 3x3
but 3x2 = 6
