Answer:
75 degrees
Step-by-step explanation:
Use trigonometry
we are given opposite(27) and hypotenuse(28), so use sin
sin=opp/hyp
sin(x)=27/28
x=arcsin(27/28)
x=74.64111442
Not sure if there're any answer choices of some sort,
but if the angle a and angle b are supplementary, that means when you add their measures together they must equal 180.

Answer:

Step-by-step explanation:
we know that
The <u><em>Trapezoid Mid-segment Theorem</em></u>. states that the length of the mid-segment is equal to the sum of the base lengths divided by two.
so

we have

substitute the given values

This is just one of many ways for this to be done
36.78 can also be written as 36 and 78/100 or 3678/100
2.4 can be written as 2 and 4/100 or 204/100
so we have 3678/100 ÷ 204/100
to divide fractions, you just have to flip the second fraction and multiply across
3678/100 * 204/100
750312/10000
Simplified that would be 75 and 312/10000
hope this helped
