Question

What is the measure of the unknown angle?

Answer 1

AnSweR:-

• Option C. 30°

☞ Sum of interior angles in a ∆le measures 180°

Let's, Unknown Angle be x

→ x+40°+110° = 180°

→ x+150° = 180°

→ x = 180°-150°

→ x = 30°

Answer 2

Answer :-

Given,

angles = 40°

and 110°

Let the third angle be x

________________________________

Now, the property says that sum of all interior angles in a triangle = 180°

So, we can write that

40° + 110° + x° = 180°

150° + x° = 180°

x° = 180° - 150°

x° = 30°
