Supplementary angles add up to 180 degrees. Using this, we can set up an equation.

Angle 1 + Angle 2=180
124+(2x+4)=180
2x+128=180
2x=52
x=26

The value of x is 26

I'm having a hard time with my geometry class. Please help me!

Answer:

Angle EFG = 82 degrees; Angle GFH = 98 degrees

Step-by-step explanation:

Linear pairs are angles that are placed side by side. When you add them together, you get 180 degrees.

Show work:

3n + 22 + 4n + 18 = 180

7n + 40 = 180

7n = 140

n = 20

Plug in the variable:

Angle EFG:

3(20) + 22

60 + 22

Angle EFG = 82 degrees

Angle GFH

4(20) + 18

80 + 18

Angle GFH = 98

Check:

98+ 82 = 180 degrees

180 degrees was the total so the answer is correct.
