Question

fobserv the following figure
and find x ​

Answer 1

Answer:

Measurement of one angle - 100°

So, measurement of opposite angle = 100°

Total measure of angles in a straight line - 180°

So, value of x would be

180 - 100

= x = 80°.

Answer 2

Answer:

80 degree

Step-by-step explanation:

100 degree's corresponding angle would be the one above x.

This makes 100 degree + x = 180 (as they are on a straight line)

100 + x = 180

X = 180 - 100 = 80 degree *
