Question

On a pentagonal lot, when interior angles are put in increasing order, each differs from the next by 5 degrees. Find the measure of the smallest interior angle of the field

Select the appropriate response:

A) 118
B) 98
C) 103
D) 108

Answer 1

B) 98°

Explanation:

Sum of interior angles of a Pentagon:

(5 - 2) × 180

540

Let the smallest angle be x

x + x+5 + x+10 + x+15 + x+20 = 540

5x + 50 = 540

5x = 490

x = 98°
