A:
Answer:m<A = 70 degStep-by-step explanation:The sum of the measures of the angles of a triangle is 180 deg. Add the three measures and set equal to 180. Solve for x. then use the value of x and the expression for m<A to find the measure of angle A.m<A + m<B + m<C = 1805x - 25 + 2x + 10 + 3x + 5 = 18010x - 10 = 18010x = 190x = 19m<A = 5x - 25 = 5(19) - 25 = 95 - 25 = 70Answer: m<A = 70 deg
