Question

Help me please please please!!!

What formula should be used to calculate an unknown side of a right angled triangle
when the hypotenuse (c) and one other side (b) are known?

a) Oa^2 = b^2-c^2

b) Oa^2 = c^2 + b^2

c) Oa^2 = c^2-b^2

d) Oc^2 = a^2 - b^2

e) Oc^2 = b^2- a^2

Answer 1

c) Oa^2 = c^2-b^2

Explanation:

the formula of finding hypotenuse (c) is

c^2 = a^2 + b^2

that means c^2 - b^2 = a^2

a^2 = c^2 - b^2.

Answer 2

C is the correct answer

because it would be the hypotenuse c squared minus the side b squared

The sum of a squared plus b squared equals c squared
