Answer 2

Step by step explanation :-

Given to solve the two questions

Question- 1

Solution :-

We have to find the value of x . If you observe the picture x forms a linear pair and it is a Staright line . Linear pair is nothing but Sum of two angles is 180°

Hence The two angles sum is 180°

So,

x + 76 = 180°

x = 180°-76°

x = 104°

So, the value of x is 104°

Question - 2

Solution :-

If you observe the picture It forms a 90° and its bisect each other Hence it sum should be equal to 90°

So,

x + 69° = 90°

x = 90°- 69°

x = 21°

So, the value of x is 21°
