Answer:

x° = 10°

5x° = 50°

2x° = 20°

Explanation:

We know that the angles of a triangle are equal to 180°, so we can set up an equation

(Given) 110° + 5x° + 2x° = 180°

(Subtract 110 from both sides) 5x° + 2x° = 70°

(Combine like terms) 7x° = 70°

(Divide both sides by 7) x = 10°

Now we can fill it in.

x° = 10°

5x° = 5(10)° = 50°

2x° = 2(10)° = 20°
