IM RUNNING OUT OF TIME AND I ONLY HAVE A FEW MINUTES LEFT PLEASE HELP ME!!! IM GIVING 15 POINTS

x = 25

<HKL  = 102

Step-by-step explanation:

<LKH + <HKJ = 180 since the two angles form a straight line

<LKH + <HKJ = 180

4x+2 + 78 = 180

Combine like terms

4x+80 =180

Subtract 80 from each side

4x+80-80=180-80

4x= 100

Divide by 4

4x/4 = 100/4

x = 25

<LKH  = 4x+2 = 4*25 +2 = 100+2 = 102

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
