Question

Two adjacent angles of a parallelogram are (3x-4)and (3x+16)find the value of x and hence find the measure of each of its angle

Answer 1

$3x - 4 + 3x + 16 = 180 \\ 6x + 12 = 180 \\ x + 2 = 30 \\ x = 30 - 2 = 28 \\ now. \\ 3 \times 28 - 4 = 84 - 4 = 80 \\ 3 \times 28 + 16 = 84 + 16 = 100 \\ i \: hope \: your \: quetion \: of \: answer \: is \: right$
