Answer:
The Length of the rectangle is 7 feet
Width of the rectangle is 11 feet
Step-by-step explanation:
the perimeter of a rectangle window is 36 feet.
Perimeter = 36 feet
the width of the window is 4 feet more than the the length
Let L be the length of the window
Perimeter of the rectangle = 2(length)+2(width)
Perimeter =
Replace perimeter by 36
Subtract 8 on both sides
Divide both sides by 4
L= 7
The Length of the rectangle is 7 feet
Width =
Width of the rectangle is 11 feet

If angle 1 and angle 2 are <u>complementary, </u>then they add up to 90 degrees. We are given that angle 2 equals 52 degrees.
So we subtract and get our answer:
38
That's NOT the final answer.
The next step is:
Angle 1 and angle 3 are vertical angles.
Vertical angles are congruent.
So if angle 1 is 38, then angle 3 is also 38.
Now, supplementary angles add up to 180 degrees.
So that's the answer:
180-38=142
142 is the supplement of angle 3.
Hope it helps! :)
