Question

in the given figure find X Y or Z (whichever is required).

Answer 1

x=?
180-130=50 (linear pair)
as the 2 sides are equal so angles formed by them will also be equal so,
.....by angle sum property
x+50+50=180
x=180-100
x=80

hope it helps!!!!!
pls mrk as brainlies

pls follow...

Answer 2

Answer:

Step-by-step explanation:

By looking at the above figure it is clear that it is an isosceles triangle

So the two angles opposite to two equal sides are equal.

now if u find one angle it is easy to get the remaining angles

Given 130 which is an exterior angle.

by looking at the figure it is clear that it makes a straight angle with the base of the traingle.

So the angle beside 130 will be 50 wgich is 180-130

so the other opposite to it will also be 50

now Sum of angles ina traingle is 180

50+50+x=180

x=80
