Answer:
1. 10 2. 62ft. 3. x=9 4. 7.5
Explanation:
1. Since the are still equal, you would have to do 50/5 and they did 25/5=5.
50/5=10. Or just do 5*2. (Or 50/25 is 2 so h is 10 so 10/5=2)
2. They give you that 2 sides of both triangles are equal. They also give equal angles. This means the triangles are equal and you can say that RS=62 ft.
3. They give that GH is equal to JK. And GH is 7x+18 and JK is 81.
So 7x+18=81 and x=9.
4. We can do 11.5/3.2=around 3.59 3.59*2.1=is around 7.5
