Question

I NEED HELP! PLEASE

Answer 1

The diagram from problem 1 is missing. So I'll only answer problem 2.

Let x be the length of the unknown segment (labeled with a question mark)

If you add the parallel bases of any trapezoid, then divide by 2, you'll get the length of the midsegment.

So,

(base1+base2)/2 = midsegment

(x+2.92)/2 = 3.98

x+2.92 = 3.98*2 .... multiply both sides by 2

x+2.92 = 7.96

x = 7.96-2.92 ...... subtract 2.92 from both sides

x = 5.04

Answer: Choice A) 5.04
