Question

What is the value of x?

Answer 1

Answer:

24

Step-by-step explanation:

The vertically opposite angles make it possible to say that the two triangles are similar. The reason is that you are give 1 pair of angles being equal and the vertically opposite angles make a second pair. By AA, the triangles are similar.

Hint: always put the line labeled x in the numerator of the proportion that you set up.

so

x/8 = 15/5    For just this question reduce the right side

x/8 = 3         Now multiply both sides by 8

8*x/8 = 3*8  Do the multiplicaton

x = 24
