Question

Find the length of the third side

Answer 1

• 8.24

Explanation:

We can use Pythagoras theorem here,

• (Perpendicular)² + (Base)² = (hyp.)²

According to the question we have

• Base = 16
• Hypotenuse = 18

Plugging the required values,

(P)² + (16)² = (18)²

(P)² + 256 = 324

(P)² = 324 - 256

(P)² = 68

P = √68

P = 8.24

Therefore the length of the third side is 8.24
