Answer:

Angle A: 60

Angle B: 30

Angle C: 90

Step-by-step explanation:

To figure out the angles, you need to set up an equation:

180 = x + x + 30 + x + 60

Add like terms:

180 = 3x+ 90

Solve for x

90 = 3x

divide by 3 to get x

30 = x

So, x is 30, and angle a is angle b plus 30, which is 60. angle c is x plus 60, which is 90.
