Answer:
Part 1) A>T
Part 2) MO<SM
Part 3) SM=MO
Explanation:
Part 1)
If SM> MO
then
m<A>m<T -------> The measure of angle A is an obtuse angle
Part 2)
If A> T
then
SM> MO -----> see part 1)
rewrite
MO<SM
Part 3)
If A=T
then
Triangle ASM and triangle TMO are congruent by SAS similarity postulate
therefore
SM=MO
