Question

find the values of unknowns x,y,z,if ABCD is a parallelogram ​

Answer 1

Answer:

y is 105⁰

because straight line is 180⁰

so 180⁰ - 75⁰ = 105⁰

x will be 105⁰

because angle ADC will be 75⁰ because it's vertically opposite angles

z will be 80 ⁰

because all the side of the quadrilateral makes 360⁰

so 75 + 75 =150

360 -150 = 160

and 160⁰ ÷ 2 = 80 because BAD and BCD are equal because they are vertically opposite angles
