Answer:
RS = 2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
RS² + RT² = TS² , that is
RS² + 6² = 8²
RS² + 36 = 64 ( subtract 36 from both sides )
RS² = 28 ( take the square root of both sides )
RS =
=
= 2
≈ 5.3 ( to 1 dec. place )
It would be C. You would multiply X by 2 and then subtract 15.
the answer is 16 because .80 times 20 is 16
Answer:
1395
Step-by-step explanation:
5 surfaces of the cuboid can be seen,so 5*l^2
4 surfaces of triangle = 4* 1/2 * 15 * 9
