Answer:
A = 12.5 units squared
Step-by-step explanation:
A = (a + b)/2(h)
A = (7.5 + 2.5)/2(2.5)
A = 10/2(2.5)
A = 5(2.5)
A = 12.5 units squared
The sum of the interior and exterior angle need to equal 180 degrees.
Let the exterior angle = X
You are told the interior angle = 38x +24
Now you have x + 38x +24 = 180
Combine like terms:
39x +24 = 180
Subtract 24 from each side:
39x = 156
Divide both sides by 39:
x = 156 / 39
x = 4
The number of sides is found by dividing 360 by the exterior angle:
360 / 4 = 90
There are 90 sides.
Y/9=44/54
9(Y/9)=9(44/54)
Y=7 1/3 or 22/3
