Question

Having problems with this

Answer 1

Answer:

45

Step-by-step explanation:

Since angles 4 and 2 are the same, we will have to do x+30 is = to 2x+15. After that x= 15. Substitute x in x+30. Which results in 45

Answer 2

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.

$(15)+30$

$=45$
