Please help! angleEFG and angleGFH are a linear pair, mangleEFG=s2n+22, and mangleGFH=4n+38. What are mangleEFG and mangleGFH?

Step-by-step explanation:

We know that a linear pair is pair of angles whose sum is 180°.

Given, ∠ EFG and ∠ GFH are a linear pair

 and

By definition of linear pair.

Now,

Hence,

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
