Answer:
8 cm
Step-by-step explanation:
We can use the Pythagorean theorem to solve since we have a right triangle
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 +6^2 = 10^2
a^2 +36 = 100
a^2 = 100-36
a^2 = 64
Taking the square root of each side
sqrt(a^2) = sqrt(64)
a =8
Pentagons have five sides, so 5*7 is 35 units
I got none of the above my answer is 1.6 BTUs/ft3. I did 400 x 8 x 3 for total BTUs = 9600 btus and the volume of the room was 20 x 30 x10 ft = 6000 cu ft so 9600/6000= 1.6 BTUs/ft3
Answer:
404.990 in^2
Step-by-step explanation:
I think, I cant be 100% sure but I'm pretty sure that's the answer, sorry if I'm wrong
The sides must be 1/2 because 1/2 ^ 2 = 1/4. 1/2 + 1/2 + 1/2 + 1/2= 2 which will be your perimeter. If this is right could you possibly give me brainliest? Hope this helped.
