Question

a. Find the value of a. b. Find the value of the marked angles.

Answer 1

Step-by-step explanation:

We can see that they are vertically opposite angles so they are equal. then

6a + 10° = 3a + 55°

6a - 3a = 55° - 10°

3a = 45°

Therefore a = 15°

Answer 2

Answer:

I agree. A is 15 degrees.
