Question

Find the length of x

Answer 1

Answer:

$x=3\frac{1}{2}$

Step-by-step explanation:

$\frac{4}{2} :\frac{7}{x}$

x · 4 = 7 · 2

4x = 14

4x ÷ 4 = 14 ÷ 4

x = 3.5

Answer 2

Answer:

7/2 =x

Step-by-step 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
