Question

From the figure, find the measure of ‘a’​

Answer 1

Answer:

The answer to this question is a = 30

Step-by-step explanation:

The angles are linear pairs. so the sum of the two angles is = 180°

Therefore

5a + 5 + 3a - 65 = 180°

8a - 60 = 180°

8a = 240°

a = 240/8

a = 30

Therefore The answer is 30.

Answer 2

Answer:

From the figure, the measure of ‘a’​ is 30 degree.

Step-by-step explanation:

In the figure we need to find the value of a .

Here , we can see that there are two angles which are placed on a straight line.

We know that sum of two angles lied on a straight line is 180 degree.

Here two angles are 5a+5 degree and 3a-65 degree.

According to the rule ,

5a+5+3a-65 = 180.

or , 8a - 60 = 180.

or , 8a = 240.

or, a = 30.

From the figure, the measure of ‘a’​ is 30 degree.
