Answer:
The answer is 230 square feet.
Step-by-step explanation:
Find the area of the bases, and the total of it is 280. I then subtracted 50 because the "covers" area is 50. That gives you the surface area without the cover
230 square feet
The surface area is found by finding the area of each surface and adding them together.
The front and back faces have areas of 10(6) = 60 feet. There are two, so this is 2(60) = 120 square feet.
The right and left faces have areas of 5(6) = 30 feet. There are two, so this is 2(30) = 60 square feet.
The bottom face has an area of 10(5) = 50 feet.
This gives us a total area of 120+60+50 = 180+50 = 230 square feet.
10x is equal to 100 so 100+6=106
then
4x is equal to 8 so 4+18=22
so it's 128
all angles of a triangle sum to 180
180 = 15x + 24x +21x
180=60x
solve for x
then substitute that for 24(x) to get the angle
i agree
