Question

A

C
Find the value of c.
b
a = 3 b=4
First, set up your equation.
a² + b² = c²
² = c²
2
[?]²+
Hint: Plug in the value of a.

Answer 1

• 5

Explanation:

Put the values

a = 3 as well as b = 4

• (a)² + (b)² = c²
• (3)² + (4)² = c²
• 9 + 16 = c²
• 25 = c²
• 
  `√(25) \: = {c}^(2)`
• 5 = c

Proof:

(3)² + (4)² = 5²

9 + 16 = 25

25 = 25

Hence verified, that a² + b² = c²
