Perhaps it is July, I think it is the hotest month of summer.
Answer:
28 centimeters.
Step-by-step explanation:
Let w be width of desk.
We have been given that the bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk is 791 square centimeters long.
Since the area of trapezoid is half the sum of parallel sides times its height.
, where
h= Height of trapezoid,
a and b= Length of parallel sides of trapezoid.
We have been given that the height of the trapezoid is the width of the desk.
Upon substituting our given vales in above formula we will get,




Therefore, the width of trapezoid is 28 centimeters.
BAC and CAD are adjacent angles, because they share a common vertex (A) and a common side AC, (an no other common points but the points on side AC).
The 2 adjacent angles form a new larger angle (BAD), whose measure is the sum of the measures of the adjacent angles.
This is called the "Angle Addition Postulate"
Answer: A
All you have to do is subtract 18.5 from 32 = 13.5 and then divide that number by 2 for each side of the poster, 13.5 / 2 = 6.75 inches
