The answer is that they are similar triangles
Answer:
8
Step-by-step explanation:
E = 15, V = 9, F =?
By Euler's rule, we have:
F + V - E = 2
F + 9 - 15 = 2
F - 6 = 2
F = 6 + 2
F = 8

E. 6+6=12 therefore not a triangle
Answer:
B
Step-by-step explanation:
You use tangent, and you set up an equation ,with h = height. You get "tan(64) = h/75" You multiply both sides by 75 and get "75tan(64) = h" You put that into a calculator, and get h is approx. 154, so B
