Question

8. Find x, using the following figure. Give reason to support your answer
Set B​

Answer 1

Answer:

According to the theorem :

The exterior angle of a triangle is the sum of its opposite interior angles.

So x = 64°- 35°

Thus the angle x is 29°.

Answer 2

Let the unknown angle be y

so

Therefore to find y

180 degree minus 64 = 116 degree = y

Now as we know Y is 116 to find X follow these steps-

Step 1. 116 plus 35 that is 151

Step2. 180 minus 151 that is 29 degree that is your answer.
