Answer:

50 in

Explanation:

We are given that

S and E are the midpoints of AB and AM.

We have to find the perimeter of triangle BAM by using the properties of midsegments.

EM=9 in

SE=7 in

E is the midpoint of side AM.

Therefore,EM=AE=9

AM=AE+EM=9+9=18 in

S is the mid-point of AB therefore,

AS=SB

By mid- segment theorem

SE is parallel to BM and


SE=(1)/(2) BM


BM=2* SE=2* 7=14 in


\angle ABM+\angle AMB+\angle BAM=180^(\circ)

Triangle angle sum property


40+70+\angle AMB=180

Angle AMB=
180-70-40=70^(\circ)

AB=AM ( Sides which make equal angles are equal)

AB=18 in

Perimeter of triangle= Sum of all threes sides

Perimeter of triangle BAM=AB+BM+AM

Substitute the values then we get

Perimeter of triangle BAM=18+14+18=50 in

S and e are the midpoints of ba and am respectively use the properties of midsegments-example-1
