The answer is the second answer choice, an = -13 + 5(n - 1)
Answer:
I believe the answer will be 63 degrees not 100% sure tho
Step-by-step explanation:
The reason is because triangle FHE measures 27 degrees it looks like FHE is a right triangle so there needs to be a total of 90 degrees in a right triangle so 90-27=63 like I said not 100% correct
Part a : Net A because when you fold it up it will look like the wanted prism
Part b : AB = 3 in
BC = 5 in
CD = 7.2 in
Part c : area of one triangle = 4*3 = 12 / 2 = 6
6 * 2 = 12 (because there are 2 triangles)
7.2 * 3 = 21.6
7.2 * 4 = 28.8
7.2 * 5 = 36
Add them all up : 12+21.6+28.8+36 = 98.4
So surface area is 98.4 in
The answer is 13.
STEPS:
√ (3 - 8)^2 + (8 - (-4) )^2
√ (-5)^2 + (12)^2
√ 25 + 144
√ 139
13
