Ok... to find the total surface area we have to realize a couple of things. First it's a triangular prism so we are dealing with 5 sides. Also the triangular sides are going to be congruent so all the side Lengths will also be congruent. The rectangular sides of the prism will have congruence as well. Lastly we have to know that to find the total surface area, you have to find the area of each side and add them together....
First the triangles. The area formula for a triangle is a = 1/2 base × height.
Since they are right triangles, the base and height are the legs of the right angle, so...
a = 1/2 (8 × 15)
a = 4 × 15 = 60 in^2
Don't forget we have 2 of them so surface area of both is 120 in^2.
Now the rectangles...
a = base × height
1) a= 13 × 8 = 104 in^2
2) a = 15 × 13 = 195 in^2
3) a = 13 × 17 = 221 in ^2
Now add them all up...
104 + 195 + 221 + 120 =
640 in^2 total surface area
Answer:
1. Diameter = VS VCS (depends on wether they are counting c as part of the segment)
2. Secant line= PQ
3. Secant Segment= QW
Hope this helped

B and D
Step-by-step explanation:
Answer:
177
Step-by-step explanation:
the number of sit-ups is going up in 4s , so if i take the 33 sit ups she does on the 5th day i add 4 to that 12 times , so you just do 33+12 and multiply that by 7 since thats how many days she has until 12.
I think it’s B (0, 0) (5, -3), (4, 1).
