Question

Given a pair of similar triangles, find the missing length x and the missing angles A, B, and C.

Answer 1

find the ratio between the two triangles:

40 on the left corresponds to 50 on the right = 40/50 = .8

.8 is the fixed ratio between these two triangles.

to find x:

43 x .8 = 34.4

x = 34.4

"angles of similar triangles are always congruent."

a: 63

b: 88

c: 29
