Question

In triangle ABC, m<A = 8x +12, m<B = 5x+14, m<C = 2x +4. What is the m<A ? Need help....please

Answer 1

Triangle
m<A + m<B + m<C = 180
8x +12 + 5x+14 + 2x +4 = 180
15x + 30 = 180
15x = 180 -30
15x = 150
    x = 10

m<A   = 8x +12
m<A   = 8(10) +12
m<A = 80 + 12
m<A = 92

answer
m<A = 92
