15/17. The value (ratio) of cos A is 15/17.
The trigonometric ratios of an acute angle are, basically, the sine, the cosine and the tangent. They are defined from an acute angle, α, of a right triangle, whose elements are the hypotenuse, the leg contiguous to the angle, and the leg opposite the angle.
-The sine of the angle is the opposite leg divided by the hypotenuse.
-The cosine of the angle is the adjacent leg divided by the hypotenuse.
-The tangent of the angle is the opposite leg divided by the adjacent leg or, which is the same, the sine of the angle divided by the cosine of the angle.
cos A = adjacent leg/hypothenuse = BC/AC = 15/17
<span>The
power of the root of the power of a variable can be written as a
rational power by creating a rational exponent that is the product of
the powers divided by the root. The rational exponent should be reduced
to lowest terms. For example, the seventh power of the sixth root of the
fifth power of x will be x^(7*5/6) = x^(35/6).
hope it helps

Answer:
The equation is 1/2 x + 8 = 15 ⇒ answer A
Step-by-step explanation:
* Lets explain how to solve the question
- Grace and her dad are planning to attend the state fair
- The price of an adult ticket is $15
- The price of the adult ticket is one half the price of the student ticket
plus $8
- Assume that the price of the student ticket is x
∵ The price of the student ticket is x
∵ The price of the adult ticket is half the price of the student ticket
x plus 8
- lets multiply half by x and then add the result by 8
∴ The price of the adult ticket = 1/2 x + 8
∵ The price of the adult ticket is $15
- Equate the expression of the price of the adult ticket by the price of
the adult ticket
∴ 1/2 x + 8 = 15
* The equation to determine how much Grace will pay for a student
ticket is 1/2 x + 8 = 15
∴ The answer is choice A
