Answer:
Explanation:
We will use to midsegment theorem to solve this question.
Midsegment theorem,
Segment joining the midpoints of two sides of a triangle, is parallel and and measure the half of the the third side.
7). HE is the midsegment.
HE =

=

= 40
8). ED =

=

= 50
9). HD =

TU = 2(HD)
= 2(80)
= 160
10). TE =

=

= 80
