Answer:
f = 2
Step-by-step explanation:
0.3 = 0.5f - 0.7
1.0 = 0.5f
2 = f
Check:
0.3 = 0.5(2) - 0.7
0.3 = 1 - 0.7
0.3 = 0.3

Answer:
he sum of the angles in all these triangles will be n x 180 degrees. The sum of the angles around the interior point is clearly 360 degrees, so the sum of the polygon’s angles will be (180n)-360 = (n-2) x 180 degrees.Here we have (n-2) x 180 = 2160, so n-2 = 12. So the polygon has 14 sides. 606 views
