Question

Having problems with this

Answer 1

45

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

45°

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`
