Answer:
m<2 = 20
Step-by-step explanation:
XY divided angle WXZ into two angles represented by <1 and <2
Now, <1 is three times <2 so if we let x represent <2 angle 1 would be represented with 3x
m<1 + m<2 = m<WXZ
3x + x = 80 add like terms
4x = 80 divide both sides by 4
x = 20 so the measure of angle 2 is 20
