The four interior angles make a sum of 360
x+10+3x+2x+x=360
7x=350
x=50
The side length of the new square would be 9. When you dialate you multiply by the square factor, so 1/2 times 18 equals 9.
You can use a protractor to solve for the angles
Slope = (-2 + 4)/(-2-2) = 2/-4 = -1/2
y = mx + b
so
b = y - mx
b = -2 -(-1/2)(-2)
b = -2 - 1
b = - 3
equation
y = -1/2x - 3
answer is B.
y = -1/2x - 3
Answer = 86.135 squared.
To find the area of this figure the best action would to divide it into three different sections, finding the area of each and then adding them all together.
First, find the area of the square in the center, which would be 60in.
Second, find the area of the half circle. You would use the formula for area of a circle. You would divide this answer by 2 since this is only half of a circle. You would get 14.135in.
Last, you would find the area of the triangle. You would multiply both sides and then divide by 2, since it’s a triangle and not a square. Area for this is 12in.
And then you would add all these together.
