Answer:

Step-by-step explanation:

(4x+39.5)° + (2y+20)° = 180°

4x + 2y = 120.5°

2x + y = 60.25° Eq. 1

Determine the expressions for the interior angles of the pentagon (see attached).

Total of interior angles of a pentagon = 540°

686.5° - 2x - 6y = 540°

2x + 6y = 146.5° Eq. 2

Subtract Eq.1 from Eq.2:

5y = 86.25°

y = 17.25°

2x + 17.25 = 60.25

x = 21.5°
