Question

Find the length of x

Answer 1

`x=3(1)/(2)`

Explanation:

`(4)/(2) :(7)/(x)`

x · 4 = 7 · 2

4x = 14

4x ÷ 4 = 14 ÷ 4

x = 3.5

Answer 2

7/2 =x

Explanation:

The triangles are similar so we can write a ratio to solve

2 4

---- = -------

x 7

Using cross products

2*7 = 4x

14 = 4x

14/4 = 4x/4

7/2 =x
