Question

the measurements of the angles of a is 48 degrees, b is (6x-28) degrees, and c is (2x) dregrees find the value of x. Then find the measures of angles b and c

Answer 1

Interior angles of a triangle add up to 180

48 + 6x - 28 + 2x = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20

< A = 48
< B = 6x - 28......6(20) - 28 = 92
< C = 2x.....2(20) = 40
