b.
72°
c.
144°
d.
108°


2. If <1 and <2 form a linear pair, m<1=100+20x, and m<2=20x, find m<2.

a.
2°
b.
40°
c.
140°
d.
180°

NUMBER 1:

d. 108°

NUMBER 2:

< 1 = 100 + 20x 

< 2 = 20x 

a linear pair sums to 180º 

so... 

(100 + 20x) + 20x = 180 

solve for x: 

40x = 80 
x = 2 

< 1 = 140º 
< 2 = 40º
