Help I'm not sure if this is the answer?<br><br> (This question is about trigonometric ratios)
dem82 [27]

Answer:

  (b) 15.32

Step-by-step explanation:

You can use your triangle sense to answer this.

The side x will always be shorter than the hypotenuse, 20. This eliminates the last two choices.

If the angle is 45°, then the sides are equal at about 0.707 times the length of the hypotenuse. That would make them 0.707×20 = 14.14. Since the angle is greater than 45°, the opposite side will be greater than 14.14. Only one answer choice fits between 14 and 20: the second choice -- 15.32.

__

The mnemonic SOH CAH TOA reminds you of the relation ...

  Sin = Opposite/Hypotenuse

  sin(50°) = x/20

  x = 20×sin(50°) . . . . multiply by 20 to find x

  x ≈ 15.32 . . . . . . . . . use your calculator to evaluate

__

The attachment is intended to show how the triangle side lengths change with angle.

Graph the solution of 2 ≥ 4 - v
Lerok [7]
For this case we have the following inequality:
 2 ≥ 4 - v
 The first thing we must do in this case is to clear the value of v.
 We have then:
 v ≥ 4 - 2
 v ≥ 2
 Therefore, the solution set is given by:
