Question

I just need help with question 2 pleaseee

Answer 1

Problem 2a: a = 12,

Problem 2b: b = 24

Explanation:

~ Problem # 2a ~

a^2 + b^2 = c^2 ⇒

a^2 + 9^2 = 15^2 ⇒

a^2 + 81 = 225 ⇒

a^2 = 144 ⇒

∴ a = √144 = 12,

~ Problem # 2b ~

a^2 + b^2 = c^2 ⇒

7^2 + b^2 = 25^2 ⇒

49 + b^2= 625 ⇒

b^2 = 576 ⇒

∴ b = √576 = 24
