Hints on solving trigonometry problems:
If no diagram is given, draw one yourself.
Mark the right angles in the diagram.
Show the sizes of the other angles and the lengths of any lines that are known
Mark the angles or sides you have to calculate.
Consider whether you need to create right triangles by drawing extra lines. For example, divide an isosceles triangle into two congruent right triangles.
Decide whether you will need Pythagorean theorem, sine, cosine or tangent.
Check that your answer is reasonable. The hypotenuse is the longest side in a right triangle.
How to use the tangent ratio to find missing sides or angles?

Answer:
-$0.90
Step-by-step explanation:
There are only two possible outcomes, winning $23 (W) or losing $15 (L). Therefore:
The probability of the player making his next 3 free throws (P(W)) is:
The probability of the player NOT making his next 3 free throws (P(L)) is:
Expected value (EV) is given by the payoff of each outcome multiplied by its probability:
The expected value of the proposition is -$0.90
<u>Answer:</u>
- <em>3.25</em>
<u>Step-by-step explanation:</u>
<em>Rule: An absolute value will always be positive. </em>
<em>=> Referring to the rule, the absolute value of |–3.25| is 3.25.</em>
