Answer:

6. Not so clear

7. 72 degrees

8. 5x + 60 = 180

9. 15 degrees

10. C

Step-by-step explanation:

7. 4x + 12 + 3x + 4 = 121 So this is the equation for the whole angle ADC.

7x + 16 = 121 Collect like terms

7x + 16 - 16 = 121 - 16 Bring 16 to the other side of the equation

7x / 7= 105 / 7

x = 15

After finding the value of x substitute it into the equation for angle ADB thus:

4 ( 15 ) + 12 = 72 DEGREES

8. When those two angles meet they form an angle in a straight line thus they sum to 180 degrees.

9. So we already know of all angles except for 1 which is the one you need to find and what you simply do is:

Add 120 + 30 + 15 = 165

Then subtract 165 from 180 because they are angles in a straight line:

180 - 165 = 15 degrees

10. The answer is C because they are adjacent and they form a perpendicular.
