I WILL GIVE BRAINLIST!! The perimeter of ABCD is 140. Solve for x, y, and z * there is picture down below*

Properties:

Find x:

Find y:

Find z:

x=10

y = 21°

z=8°

Step-by-step explanation:

we have

AB = AD, CB = CD,

AC perpendicular to DB, AC is angle bisector of DAB and DCB

Perimeter = 140

2(2x + 7 + 4x +3) = 140

6x + 10 = 70

6x = 60

x = 60/6=10

x=10

again

3y - 1 +28° =90

3y - 1 = 90° - 28°

3y - 1 = 62°

3y = 63°

y = 21°

again

4z+58°=90

4z = 90° - 58

4z = 32°

z=32/4

z=8°

step-by-step explanation: 4 cause 2+2=4
