Question

In the figure find the value
of
x + y + z
​

Answer 1

Answer:

Step-by-step explanation:

Given.,

Two angles of triangle

One is 30 and other is 65

Find ,

Angle X, angle y

Solution,

Firstly...

The some all angles of triangle=180

So ,

Angle a+b+c=180

30+65+angle c=180

95+angle c=180

Angle c=180-95

Angle c =85

Know ,

The angle of one streat line is 180 degree..

Therefore,

Angle y + angle c=180

Angle y +85=180

Angle y =180-85

Angle y = 95

Also we do same thing at here,..

Angle b+angle X =180

30+angle X =180

Angle X =180-30

Angle X =150

Hence...,

X =150

Y=95

And one more way to find exterior angle...

The some of two angles of triangle = exterior angle of third angle

I hope u can understand and also helpful to you....
