Question

Find the length of side AC. A) 5/3 B) 5/2 102 D) 52 2 S.

Answer 1

Answer:

• D. 5√2/2

Step-by-step explanation:

Given triangle is right isosceles since one of the angles is 45°

Let the AC = x, then BC = x and AB is:

• x² + x² = 5²
• 2x²=5²
• x²= 5²/2
• x = 5/√2
• x = 5√2/2

Correct option is D
