Question

ABCD is a parallelogram find x and y ​
A=3y° B=(2y-5)° C=(3x+3)°

Answer 1

Answer:

angle A = angle C ( vertically opposite)

so, 3y= 3x+3

3y-3x = 3

y-x= 1

so y= x+1

B= 2y-5°

2x+2-5

= 2x-3

then 3x+3+2x-3+3x+3+2x-3=180°

10x = 180°

x= 18°

so y= 19°

A= 57°

B= 33°

C= 57°

and D = 33°
