Answer:
x = 12
Step-by-step explanation:
20° + (6x - 2) = 90°
18° + 6x = 90°
6x = 90° - 18°
6x = 72°
x = 72°/6
x = 12
Answer:
50°
Step-by-step explanation:
1) Opposite angles are the same. Therefore,
2x-20=x+15
2x-x=15+20
x=35
2) Put x back in the equation for angle mhj
2(35)-20=50
8b+12-b=8+7b+4
7b+12=12+7b
-7b
7b-7b+12=12
-12 -12
0= 12-12
0=0
