Let's use the distance formula:
![\sqrt{ (x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%28x_%7B1%7D%20-%20x_%7B2%7D%29%5E%7B2%7D%20%2B%20%28y_%7B1%7D%20-%20y_%7B2%7D%29%5E%7B2%7D)
So it is:
AB :
![\sqrt{(-5)^2 + 8^2} = 9.43](https://tex.z-dn.net/?f=%20%5Csqrt%7B%28-5%29%5E2%20%2B%208%5E2%7D%20%3D%209.43)
BC:
![\sqrt{5^2 + 0^2 } = 5](https://tex.z-dn.net/?f=%20%5Csqrt%7B5%5E2%20%2B%200%5E2%20%7D%20%3D%205)
CA:
![\sqrt{0^2 + 8^2} = 8](https://tex.z-dn.net/?f=%20%5Csqrt%7B0%5E2%20%2B%208%5E2%7D%20%3D%208%20)
So 9.43 + 5 + 8 =22.43
Answer:
6y
Step-by-step explanation:
The two figure are squares with the same area
side = √area = √y^2 = y (with y>0 because a length can‘t be negative)
perimeter = side * 6 = y * 6 = 6y
Answer:
11 inches by 8.5 inches.
Step-by-step explanation:
1 ft = 1/2 inch on the scale drawing, so:
22 ft is equivalent to 1/2 * 22 = 11 inches.
17 ft is equivalent to 1/2 * 17 = 8.5 inches.
Answer:
5 units
Step-by-step explanation:
If DG, EG and FG are perpendicular bisectors of the sides of triangle ABC, then point G is the circumcenter of the triangle ABC and
BG = AG = CG as radii of the circumcirle.
Consider right triangle BEG. By the Pythagorean theorem,
![BG^2=EG^2+BE^2\\ \\BG^2=4^2+3^2\\ \\BG^2 =16+9\\ \\BG^2=25\\ \\BG=5\ units](https://tex.z-dn.net/?f=BG%5E2%3DEG%5E2%2BBE%5E2%5C%5C%20%5C%5CBG%5E2%3D4%5E2%2B3%5E2%5C%5C%20%5C%5CBG%5E2%20%3D16%2B9%5C%5C%20%5C%5CBG%5E2%3D25%5C%5C%20%5C%5CBG%3D5%5C%20units)
This gives us that
AG = BG = 5 units
