Answer:
120/17
Step-by-step explanation:
There are two ways to solve this problem - difficult and simple.
The difficult way is to realize that all triangles are similar and have the same angles. Then try to figure x from the ratios.
The simple way is to find the area of triangle ABC.
in this case .5*x*17=.5*8*15
simplifying by .5 and dividing by 17 we get: x=120/17
Answer: 21
Step-by-step explanation:
21=42-3r
3r-42=21
3r=21+42
3r=63
r=21
