Answer:

45°

Step-by-step explanation:

Corresponding angles are equal. ∠4 and ∠2 are equal.

x+30=2x+15

Add -x and -15 on both sides of the equation.

30-15=2x-x

15=1x

∠4 = x+30

Put x as 15 in the equation.

(15)+30

=45

What is 30/40 simplified
forsale [732]
When you're looking to simplify a fraction, the best thing to do is to find a common factor between the two numbers.
In this case, 10 is a common factor, so therefore, divide both sides by 10.

40/10= 4
Therefore, the fraction in its simplest form is 3/4
