Question

find the value of x with explaination & solution​

Answer 1

4 th-

angle ABC= 180-120degree(linear angle)

so, angle ABC= 60 degrees

It is given that AB is equal to AC, so angle B would be equal to equal to angle C(angles opposite to equal sides are equal)

angle ABC=angle C

Now in triangle ABc

Angle A.+ Angle ABC+ Angle C = 180 degree

x + 60 + 60= 180

x+120= 180

x= 60 degrees

5th-

The interior angle of 100 degree would be (180-100)=80 degree (Linear pair of angles)

The interior angle of 130 degree would be (180-130)=50 degree(Linear pair of angles)

Now in the triangle

80+50+x=180 degree( Angle sum property)

130+x=180

x=50 degrees

Hope it helps.
