Question

What is x given angle ABC~ angle DBE~ ?

Answer 1

30:50 = 3:5

x : x+25 = 3:5

25/2 x 3 = 37.5

Answer 2

Answer:

x = 37.5

Step-by-step explanation:

Find the ratio.

$\frac{x}{x+25}=\frac{30}{50}$

Cross-multiply, distribute.

$50x=30(x+25)\\\\50x=30x+750$

Subtract 30x from both sides.

$20x=750$

Divide both sides by 20.

$x=37.5$
