Question

Find x,y and z where y=z and x+y = 110​

Answer 1

Answer:

z=180-110 (linear pair)

=70

y=z

so y= 70

x+y+z=180 (angle sum property of triangle)

x+70+70=180

x=180-140

=40

Answer 2

Answer:

x=40° ,y=70° ,z=70°

Step-by-step explanation:

sum of all angles =180°

x+y+z=180°

sum of opposite angle= exterior angle

x+y=110°

x+y+z=180°

110+z=180

z=180-110

z=70°

y=z

so y=70° ,z=70° ,X=?

x+y+z=180

x+70+70=180

x+140=180

x=180-140

x=40
