Answer:
m<1=60°
m<2=39°
m<3=21°
m<4=39°
m<5=21°
Step-by-step explanation:
since triangle WZY is isosceles, this means that the measure of angle 3 is the same as measure of angle 5.
to find out what they equal:
180-138=42.
then divide by 2 since angle 3 and angle 5 are congruent.
42/2=21°.
m<3 =21° and m<5 =21°
triangle WXY is equilateral, and an equilateral triangle has 60° angles.
so, m<1=60°.
however, to find m<2 and m<4 we would have to subtract 60° from 21°:
60°-21°=39°.
so, m<2 =39°, and m<4=39°
