Answer:
The area of this composite figure is 
Step-by-step explanation:
we know that
If the composite figure is divided into two congruent trapezoids, then the area of the composite figure is equal to the area of one trapezoid multiplied by two
so
The area of the composite figure is
![A=2[\frac{1}{2}(b1+b2)h]](https://tex.z-dn.net/?f=A%3D2%5B%5Cfrac%7B1%7D%7B2%7D%28b1%2Bb2%29h%5D)
substitute the values
First we write the expression:
((x / 3) - (y / 4)) / ((x / 4) + (y / 3))
We multiply the numerator and the denominator of the expression by: (4) * (3).
We have then:
(((4) * (3)) * ((x / 3) - (y / 4))) / (((4) * (3)) * ((x / 4) + (y / 3)) )
We now rewrite the expression:
(4x - 3y) / (3x + 4y)
The simplified expression is:
(4x - 3y) / (3x + 4y)
Answer is 180- (60+70) = 50°
