Question

Find the value of x in the following figure:​

Answer 1

Answer:

Here,

Step-by-step explanation:

The angle 'x' and 80° form a linear pair, so

x+80°=180°    (LP)

x=180°-80°=100°

Therefore, x=100°

Answer 2

Answer:

x = 100

Step-by-step explanation:

We all know that a straight line's angle is 180. Now, we see two angles on the straight line. One angle is 80 and the other is unknown. The unknown angle + 80º = 180º

Hence,

x = 180º - 80º = 100º
