Answer:
X=10
Step-by-step explanation:
You can subtract 180 by 110 to get 70. Then you can do 8x+30+70=180
Add 30+70 to get 100
Subtract 100 to 180 to get 80.
8x=80
You divide 8 from both sides which leaves you with x=10.

Answer:
m∠ABC = m∠EDC = 154°
Step-by-step explanation:
The roof forms and isosceles triangle and the following relationships can be observed:
m∠EDC + m∠ABC = 52 = 180
m∠ABC = m∠EDC = 64.
Since the frame of the walls make a 90 degree angle with the roof, then:
m∠CDB + 90 = m∠EDC
m∠CBD + 90 = m∠ABC
m∠ABC = m∠EDC = 64 + 90
m∠ABC = m∠EDC = 154°
