Try to draw out triangle--it helps
Need to use law of sines... this is where an angle and the side that opposes it are equal to each other. For example, Angle U is equal to 9.7
Multiply 4 and sin90 and then divide the product by 9.7

Answer:
<h2>10</h2>
Step-by-step explanation:
the combined area = area of the trapezoid + area of the triangle
=
= 6 + 4
= 10
The sum of length and width of a rectangle is half the perimeter. Here the sum of length and width is 114/2 = 57 ft.
If we add 12 ft to this total, we have a value that is 3 times the width.
The width of the sign is 69 ft/3 = 23 ft.
The length of the sign is (2·23 -12) = 34 ft.
_____
From the problem statement, using L and W for length and width:
... L = 2W -12
... P = 114 = 2(L +W)
Dividing the second equation by 2 and substituting for L, we have ...
... 57 = (2W -12) +W
... 69 = 3W . . . . . . . . add 12
... 23 = W . . . . . . . . . divide by 3
