What is the measure of angle R

 The measure of ∠R = 108.25°

Step-by-step explanation:

The sum of the interior angles of a pentagon is 540°

We can use that to set up an equation to calculate the value of x, then use that value to calculate the measure of the angle requested.

(3x + 1) + (2x + 15) + (3x + 10) + (3x -8) + (5x -2) = 540

Combine like terms

3x+ 2x+ 3x +3x + 5x + 1 + 15 +10 -8 -2 = 540

16x + 16 = 540

16x = 524

x = 32.75

The measure of Angle R is 3x -10

3(32.75) + 10

∠R = 98.25 + 10

∠R = 108.25°

the answer is d. (1.2, -4.7) on edgn
