Question

O. find the value of y in a figure
​

Answer 1

Answer:

15°

Step-by-step explanation:

Since it is a straight line, it forms 180°

180-150=30

ATQ,

2y = 30

y = 30/2

y = 15°

Answer 2

Linear Pair:

Sum of two angles situated on a line is 180°.

Explanation:

2y + 150° = 180° ( Linear Pair )

or, 2y = 180° - 150° ( By Imposing Method )

or, y = 30°/2

or, y = 15°

Answer:

The value of y is 15° .
