Question

ABCD is a parallelogram . Find angles x , y and z .

Answer 1

Answer:

Angle x is 50°, Angle y is 40° and Angle z is 30°

Step-by-step explanation:

Answer 2

angle B+angle C +angle E =180

Step-by-step explanation:

….……........(sum of all angles of triangle is 180.)

therefore, angle B+angle C+angle E =180

angle B+ 40+90= 180

therefore, angle B +130=180

angleB=180-130

therefore,. angle B=50

therefore,. angle B=X=50
