Answer:

x = 34

x + 5 = 39

4x + 5 = 141

5x + 10 = 180

Explanation:

Because the angles cover a full rotation, we can assume that their sum equals 360.

x + 5 + 4x + 5 + 5x + 10 = 360

Combining like terms:

10x + 20 = 360

10x = 340

x = 34

For the other angles, we just have to substitute:

x + 5 = 39

4x + 5 = 141

5x + 10 = 180

We can confirm this by adding them all up:

39 + 141 + 180 = 360
