Anybody know the answer to these

9514 1404 393

  9.  19.4

  10.  15.8

  11.  16.6

Step-by-step explanation:

The appropriate relations are all given. Fill in the given numbers and solve for the unknown.

9. x^2 +8^2 = 21^2

  x^2 = 441 -64 = 377

  x = √377

  x ≈ 19.4

__

10. sin(33°) = x/29

  x = 29·sin(33°)

  x ≈ 15.8

__

11. cos(55°) = x/29

  x = 29·cos(55°)

  x ≈ 16.6

seems like d

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
