True! they are corresponding angles.
Answer:
13/100
Step-by-step explanation:
Answer:
y = -1/2x + (-1)
Step-by-step explanation:
12Sqrt(3)
This is because we can find the height and base of the triangle by using 30-60-90 triangles. Because the center point bisects the 60 degree angles in each corner, we can make 30-60-90 triangles. Then using porportions, you'll find the height of the triangle is 6 and the base is 4sqrt(3). Then use the area of a triangle formula.
Assuming the square and the semicircle aren't merged somehow, and we need to calculate their full area, we should take into account:
Area of a square:
(Side length)² = 22² = 484 square inches
Area of a circle with a diameter of 22inch:
3'14 · (radius)² = 3'14 · 11² = 379'94 square inches
Since we have half a circle, the total areas to add will be:
1/2 · 379'94 + 484 = 673'97
