Answer:
7
Step-by-step explanation:
The angle sum property of a triangle is the sum of the interior angles of the given triangle.
The total sum of the interior angels of a triangle =180
The area of the trapezoid is given by:
A = (1/2) * (b1 + b2) * (h)
Where,
b1, b2: bases of the trapezoid
h: height
Substituting values we have:
91 = (1/2) * ((2 * 7) + b2) * (7)
Rewriting we have:
91 = (1/2) * (14 + b2) * (7)
(2/7) * 91 = 14 + b2
b2 = (2/7) * 91 - 14
b2 = 12 m
Answer:
The measure of the other base of the trapezoid is:
b2 = 12 m
Answer:
58.5
Step-by-step explanation:
since a triangle consists 180 degrees, 180-90-31.5 would equal 58.5
