Answer:
#4
<u>Exterior angles of a polygon sum to 360</u>
- 94 + 56 + 4.5x + x + 1.5x = 360
- 150 + 7x = 360
- 7x = 210
- x = 30
#5
<u>Sum of interior angles of a pentagon is:</u>
<u>Sum of interior angles of a given pentagon:</u>
- 72 + 3x + 89 + 99 + 2x = 540
- 5x + 260 = 540
- 5x = 280
- x = 280/5
- x = 56
120+72+24+24+96=336 cm cubed
