Answer 1

1: Identify the angle.

The following angle is a 90.

2: Set up the equation.

x + (3x + 10) = 90

3: Combine like terms.

4x + 10 = 90

4: Solve for x.

4x + 10 = 90

     -10 =   - 10

--------------------------

4x = 80

4          4

x = 20

Your answer is x = 20.

Hope this helps! Have a good day/night! c:

Answer 2

Add all the similar terms
4x+10 = 90
4x = 90 -10
4x = 80
80/4= 20
x = 20

Then substitute x = 20 in to make sure it’s right (:
it is thought so don’t worry (:
