Question

LOTS OF POINTS!!!!!!!!

Please help asap!!!!! I need to solve for x

Answer 1

x = 1 11/15

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
