If m∠8=23°, find the measure of each missing angle. Give your reasoning. m∠1=?
m∠2=?
m∠3=?
m∠4=?
m∠5=?
m∠6=?
m∠7=?

m∠1= 157°(Angles 1 and 7 are alternate exterior.)

m∠2= 23°(Angles 8 and 2 are alternate exterior.)

m∠3=  157°(Angles 1 and 3 are vertical.)

m∠4=  23°(Angles 6 and 4 are alternate interior.)

m∠5=  157°(Angles 5 and 7 are congruent.)

m∠6=  23°(Angles 6 and 8 are vertical.)

m∠7= 157°(Angles 7 and 8 are on a straight line.)

Step-by-step explanation:

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
