Find the values x, y, and z

Step-by-step explanation:

x°+y°=90°

mSquare =360°

z°= 360°-(90°+90°+51°)

z°=360°-231°

z°=129°

mTriangle=180°

angle in base of triangle is equal

because this is isosceles triangle

so 2y°+z°=180°

2y°+129=180°

2y°=180°-129°

2y°=51°

y°=51°/2

y°=25.5°

x°+y°=90°

so x°=90°-y°

x°=90°-25.5°

x°=64.5°

final

x=64.5°,y=25.5°,z=129°

hope this .
