Both angles are supplementary, which means that they both add up to 180°. To find the value of x, simply put the two equations together like this:

A.)
26x - 7 + 10x + 7 = 180

The -7 and +7 cancel each other out, which leaves us with


10x + 26x = 180

-->
36x = 180

180 is 36 times bigger than x, so divide both sides by 36:


x = (180)/(36)

x = 5

Now plug in the value of x:

B.)
26(5) - 7 = 130 - 7 = 123°

C.)
10(5) + 7 = 50 + 7 = 57°

To check your work, add them both up.
123 + 57 = 180 degrees

I hope you found this helpful. : )

Answer:

x=5

m∠HJL =123°

m∠LJK=57°

Explanation:

m∠HJL=(26x-7)° and m∠LJK=(10x+7)°

∠HJL and ∠LJK are linear pair . the sum of angles = 180 degree

m∠HJL+ m∠LJK=180 degree


(26x-7) +(10x+7)=180

Combine like terms and solve for x


36x=180

Divide by 36 on both sides

x=5

m∠HJL=(26x-7)=26(5)-7=123°

m∠LJK=(10x+7)=10(5)+7=57°
