Question

Fine the value of a in the image below.​

Answer 1

metre it with scale and then write its value with points

Answer 2

Explanation:

a + a + a + 120 + 90 = 360

Combine like terms

3a + 210 = 360

Subtract 210 from both sides

3a = 360 - 210

3a = 150

Divide both sides by 3

a = 150/3

a = 50°
