Question

ABCD is a parallelogram. Find values of x,y,z ( a,c,d) (b value 125°)​

Answer 1

Answer:

a = 55

b = 125

c = 55

d = 125

Step-by-step explanation:

By rule of parallelograms, angle d is also equal to 125. So, b + d = 250. Also, all quadrilaterals inner angles sum must be 360. So we get

c + a + 250 = 360

Subtracting 250 from both sides gives us

c + a = 110

Again, by rule of parallelograms, c = a. So,

a = 55

b = 125

c = 55

d = 125

Answer 2

Step-by-step explanation:

B = D = 125° ( opp. angles in parallelogram are equal)

A = C = 55°. (same ,. angle sum prop.)
