Question

in a triangle xyz if angle x=40 find the other also y=z

Answer 1

Hi ,

In Triangle XYZ ,

< X + < Y + < Z = 180°

40° + Y + Y = 180°

2Y = 180 - 40

2Y = 140

Y = 140/2

Y = 70°

Therefore ,

X = 40° ,

Y = Z = 70°

I hope this helps you.

Answer 2

hey friend!

angle sum property will help here

angle x+angle y+angle z=180

the value of angle x is given and it has said that angle y and z are same so lets take angle y and z as equal and let us write is as b.

40+b=180
b=180-40=140

the value  of b i.e the sum of angle y and z is 140
so to find the value of angle y and z when both are same divide 140 by 2

140/2=70


value of angle y and z is 70 degree

Hope it helps!
