Question

a. 3
b. 4
c. 6
d. 8

Answer 1

Answer:

D. x = 8

Explanation:

Triangle ACD is an enlarged triangle of Triangle ABE

so an equation can be formed to solve this:

$\frac{3x}{30}$ = $\frac{48}{30+30}$

$\frac{3x}{30}$ = $\frac{48}{60}$

3x * 60 = 48 * 30

180x = 1440

x = 1440 ÷ 180

x = 8

Answer 2

Triangle ACD is an enlarged triangle of Triangle ABE

so an equation can be formed to solve this:

$\frac{3x}{30} = \frac{48}{30 + 30}$

$\frac{3x}{30} = \frac{48}{60}$

$\frac{3x}{60} = \frac{48}{30}$

$180x = 1440$

$x = \frac{1440}{180}$

$x = 8$
