Answer:

R = 134

Explanation:

This is a 5 sided figure. The interior angles add to (n – 2)180 where n is the number of sides

(5-2) * 180 = 540

Add up all the angles and set it equal to 540

R+ 78+109+113+106 = 540

Combine like terms

R + 406 = 540

Subtract 406 from each side

R +406-406 = 540-406

R = 134
