Complimentary angles add up 90°
let one of the angles be x, the 2nd angle will be (x+4)
thus the total sum will be:
x+(x+4)=90
2x+4=90
thus the right equation is:
<span>B. 2x + 4 = 90</span>
Answer:
100+20π
Step-by-step explanation:
Find the diagram attached.
Perimeter of a square =4L
L is the side length of a square
From the diagram;
L = 10
Perimeter of a square = 4(10) = 40
Perimeter of 3 squares = 3(40) = 120
2 semi circle = a circle
Perimeter of a circle= 2πr
radius of the Circle = length of a side of the square.
Area of the circle = 2π(10)= 20π
Perimeter of the shape = Perimeter of the two semicircle + area of the 4squares = 100+20π
