Surface area is the sum of areas of 4 triangles.
<u>Each triangle has:</u>
<u>Area of each triangle:</u>
- A = 1/2bh
- A = 1/2*9*7.79 = 35.055 ft²
<u>Surface area:</u>
- S = 4*35.055 = 140.22 ft²
The sum of the measures of the exterior angles of a polygon, taken one per vertex, is 360.
z - 13 + z + 10 + z = 360
3z - 3 = 360
3z = 363
z = 121
z - 13 = 121 - 13 = 108
Answer: z - 13 = 108 degrees
