Answer:

a) 2(x+15) + 3x + 10 + 5x = 180

b) x = 14

c) ∡A = 58°, ∡B = 52°, ∡C = 70°

Step-by-step explanation:

a) 180° in a triangle, so adding the three ∡s together will get you 180°.

b) Do 2(x+15) before you combine like terms, then divide both sides by the coefficient of x.

c) Substitute the value of x for each expression.
