Question

in the adjacent figure DE//BC angle ADE=60degree and angle c=70 degree find the values of X degree y degree and z degree

Answer 1

angle ADE=angle ABC =60° (corresponding angle)

Angle AEC = angle ACB = 70° (corresponding angle)

Angle A+ AngleB + Angle C = 180°

60° + 70° + Angle A = 180°
Angle A = 50°

so,
x= 60°
y= 70°
z= 50°
