Answer:
27 =x
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the same side of the large triangle.
x+8 10
------- = -------------------
2x-5 14
Using cross products
14 (x+8) = 10 (2x-5)
Distribute
14x+112 = 20x-50
Subtract 14x from each side
14x-14x +112 = 20x-50-14x
112 = 6x-50
Add 50 to each side
112+50 = 6x-50+50
162 = 6x
Divide by 6
162/6 =6x/6
27 =x
