The expression used in this question, 0.99c + 0.79a, is representative
of the total cost of buying any number of apples and cucumbers, Where x =
how many, 0.99c is the total cost of cucumbers when c is given as a
value, and 0.79a is the total cost of apples when a is given as a value.
Answer:
Step-by-step explanation:
<u>Trigonometric Identities</u>
<u>Trigonometric ratios</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Using the trig ratio formulas for cosine and sine:
Therefore, using the trig identities and ratios:
Answer:
X = 2
