Answer:
1. Use the Pythagorean theorem to find AD. Show your work.
AD=9
Side BD=12, and side AB=15. We know that side AB is the hypotenuse, so AD^2+144=225
225-144=81, so side AD=9
2. Find AC. Show your work.
AC=25
To find AC, we can add AD and DC
9+16=25
3. Is ΔABC a right triangle? Explain.
ABC is a right triangle because AB^2+BC^2=AC^2
Step-by-step explanation:
Answer:
1. AD=9
2.AC=25
3.ABC is a right triangle because AB^2+BC^2=AC^2

Two regular hexagons are similar. The perimeters have a ratio of 1:5. If the side of the larger hexagon has a length of 25 inches, what is the perimeter of the smaller hexagon?
Answer:
30 inches
Step-by-step explanation:
if one side of the larger hexagon is 25, multiply that by 6 to get the total perimeter. 25 x 6 = 150.
- the smaller hexagon is 1/5 the size
- 1/5 of 150 is 30
hope this helps :)

Im almost high school so thisis what I got.
i need help with this
Answer:
It's Halloweeeeen
Step-by-step explanation:
(I took Geometry before and I still have my notes). To find the area of the rectangle, you'd multiply 12 x 9 because the rEcIpE for it is length x width (A=lw). Whe you do that, you get 108.
To find the area of the triangle, you have to multiply the base and the height, then divide that by 2. The recipe for that is 1/2 base x height (A=1/2bh). The base of the triangle is equal to the height of the rectangle (which is 9). So you'd be multiplying 9x7 which equals 63, then dividing that by 2 which is 31.5.
After all that, you add 108 and 31.5 to get 139.5cm squared! Hope this helped :3
