Find the values of x,y,and z. The diagram is not to scale
Irina-Kira [14]

Answer:

x+63°+36°=180°(angle sum property in first triangle)

x+99°=180°

x=180°-99°

x=81°

x + z=180

81°+z=180°

z=180°-81°

z=99°

z+13°+y=180(angle sum property in second triangle)

99°+13°+y=180

112°+y=180°

y=180°-112°

y=68°

therefore, x=81°  z=99°  y=68°

hope it helps you
