Answer:
x = 1 11/15
Step-by-step explanation:
Using ratios of similar triangles
3 5.2
-------- = ----------
4 (5.2 + x)
Using cross products
3 * (5.2 + x) = 5.2 * 4
Distribute
15.6 + 3x = 20.8
Subtract 15.6 from each side
15.6-15.6 + 3x = 20.8 -15.6
3x =5.2
Divide each side by 3
3x/3 = 5.2/3
x = 5.2/3
x=52/30
x = 26/15
x = 1 11/15
