Question

Give my answer. I have attached the pictures of my question below

Answer 1

HEY USER,
HERE IS YOUR ANSWER :-

The right option is (2) i.e. 50 .
because both the 2 angle makes a total 180° angle .
one of them is 130° .
So, other will be 180° - 130°
= 50°

HOPE IT HELPS YOU !!!!........

Answer 2

Answer:

Concept: In this question, two concepts will be used:

1- linear pair ( sum of two angles of linear pair is 180°

2- The sum of all three angles of a triangle is 180°

Given: An image of intersecting lines that are forming triangles.

To Find: Value of 'x'

Solution: First see a triangle whose 2 exterior angles are given , their interior angle will be 180-130=50

join the adjacent line with x and find third angle

50+50+a=180

a=180-100, a=80

now in the second triangle, we have two angles and find the third x

100+50+x=180

x=30

hence, option (4),30 is the right answer to the question
