Answer:
65
Step-by-step explanation:
1. Subtract 180(the total degrees of a straight angle) by the 95 degrees.
Angle #2 is 85.
2. Add 30 degrees and 85 degrees together. You'll get 115.
3. Subtract 180 (the total degrees in a triangle) by 115.
Answer: 65
I believe it's A, C and D.
x= 55
The two angles add to 180 degrees since they form a straight line
2x+70 =180
Subtract 70 from each side
2x+70-70=180-70
2x= 110
Divide by 2
2x/2 = 110/2
