Answer:
Step-by-step explanation:
The question in English is basically find the area of the pink and blue area shown. The image is attached. This is Liza and Abby's blanket spread and we want the area of the whole shown.
<u>Solution:</u>
We want area of pink rectangle PLUS the blue region, which is a sum of lower rectangle and top triangle (if we cut it in this way).
First, area of pink rectangle:
Area = length * height
Area = 5 * 5.7
Area = 28.5
Now, the blue region, if broken down, lower portion is rectangle and upper portion is a triangle (we DISREGARD the overlapping region, of course!)
Lower Rectangle Area = length * height = 4 * 2 = 8
Upper triangle Area = 0.5 * base * height = 0.5 (4) * (6-2) = 0.5 * 4 * 4 = 8
So, blue region area = 8 + 8 = 16
<u>Total Area = 28.5 + 16 = 44.5 sq. ft.</u>

Call one of the angles = x
The other one is 180 - x
They are in the ratio of 3 to 5
Equation
3/5 = x / (180 - x)
Solve
3/5 = x / (180 - x) Cross Multiply
3*(180 - x) = 5x
540 - 3x = 5x Add 3x to both sixes
540 = 5x + 3x
540 = 8x
Divide both sides by 8
540 / 8 = x
x = 67.5
One angle is 67.5
The supplement is 180 - 67.5 = 112.5
Check
67.5/112.5 = 0.6 which is the same thing as 3/5
