Question

Pls help with this questions

Answer 1

Angle of a straight line always sum up to 180 degrees
So what you should do is add the angles that are given to you and then subtract it from 180
Working:
100 + 20 + x = 180
120 + x = 180
x = 180 - 120
x = 60 degrees


I hope this helps you and your welcome

Answer 2

X=60 degrees
the line adds up to 180 degrees in total
