Question

Find the missing side

Answer 1

Answer:

$\huge\boxed{\sf x = 8.2}$

Step-by-step explanation:

Since it is a right-angled triangle, we will apply Pythagoras Theorem.

Given are:

Base = 16

Perpendicular = x

Hypotenuse = 18

Pythagoras Theorem:

$\sf (Hypotenuse)^2=(Base)^2+(Perpendicular)^2$

(18)² = (16)² + (x)²

324 = 256 + x²

Subtract 256 to both sides

324 - 256 = x²

68 = x²

Take sqrt on both sides

8.2 = x

x = 8.2

$\rule[225]{225}{2}$
