Question

Find the measure of the exterior angle.

Answer 1

110 degrees because the other side is equal to 70° and the line is 180 so you would subtract 70 from 180 to get you 110°

Answer 2

$\huge{ \mathfrak{ Answer }}$

Exterior angle = sum of opposite interior angles,

so,

$\boxed{(t + 10 )+( t )= 180-(t + 20)}$

• $2t + 10 = 180 - t - 20$
• $2t + t = 160 - 10$
• $3t = 150$
• $t = 50$

value of t = 50°

$\boxed{Exterior \: \: angle = 180 -(t + 20)}$

• $180 - (50 + 20)$
• $180 - 70$
• $110°$

measure of exterior angle is 110°
