Question

ABCD is a parallelogram. find x and y ​

Answer 1

Answer:

x = 88°/19 and y = 93°

Step-by-step explanation:

186°+7x = 28°+60° ( opposite angles of a parallelogram are equal )

19x = 88°

x = 88°/19

12x = 55.57° + 17x = 32.43°

55.57+32.43 = 88°

Let angle B and D are y

angle A+B+C+D = 360° ( sum of interior angles of a parallelogram)

88°+y+88°+y = 360°

176°+2y = 360°

2y = 360°-176°

2y = 186°

y = 186°/2

y = 93°

Angle B and D are 93°

Therefore, x = 88°/19 and y = 93°
