Question

two adjacent angles of a parallelogram are (5x-3)° and (5x-67)°. find all the angles of the angles of the parallelogram.

Answer 1

the sum of two adjcents angles is 180

(5x-67)+(5x-3)=180

5x-67+5x-3=180

10x-70=180

10x=180+70

10x=250

x=250/10

x=25

(5*25-67) and (5*25-3)

125-67 and 125-3

58 degree and 122 degree
