Question

Find the volume of x in the triangle shown below

Answer 1

x = 109°

Explanation:

Utilise the fact that angles in a triangle add up to 180 so,

→ Form an equation

x + 23 + 48 = 180

→ Simplify

x + 71 = 180

→ Minus 72 from both sides to isolate x

x = 109°

Answer 2

109°

Explanation:

x+48+23=180

x=180-71

x=109°
