Answer:
Step-by-step explanation:
x = 180 - 72 = 108° (linear pair)
y = 72° (vertically opposite angles)
z = 180 - (90+72) = 180 - 162 = 18°
4x +31 = 35
6x +39 = 45
35 + 45 = 80
I believe it would be 80
Answer:
C.
Step-by-step explanation:
So basically set (10x-13) equal to (3x+22) and then solve for x
x=5
Plug 5 into the equations
(10(5)-13)=37
(3(5)+22)=37
These two angles are congruent due to the triangle being isosceles
37+37=74
All angles in a triangle are equal to 180 degrees
Therefore 180-74=106
Angle JKL= 106 degrees
Hope this helps :)
