Answer:
a. 26 inches by 31.2 inches
Step-by-step explanation:
The lengths(X) of the rectangular is 1.2 times longer than the width (Y), so you can put it into this equation
x= y * 1.2
x= 1.2 y
The area of the window is 811.2 square inches, so you can put this equation
x * y= 811.2
Combining both equations, you can get
x * y= 811.2
(1.2y) * y = 811.2
1.2y^2= 811.2
y^2= 676
y= 26
x= 1.2 y
x= 1.2(26)= 31.2
360/18= 20
so the answer is 20 degrees
