a =160 b=20 as linear pair of angle
mysticd:
explain how ?
how 160 , 20

Answer:
a = 100° and b = 80°
Step-by-step explanation:
If they form a linear pair,
then a + b = 180°-----------------1
a - b = 20°-------------------2
Add 1 and 2
2a = 200°
a = 200° / 2 = 100°
Substitute a = 100 in 1
you get
100+ b = 180°
b = 80°
