Given 15 cot A = 8, find sin A and sec A.​
pogonyaev

Answer:

sin A = 15/17

sec A = 17/8

Step-by-step explanation:

15 cot A = 8

First get cot A alone.

cot A = 8 / 15

Since cot is the reciprocal of tan then flip 15 and 8.

tan A = 15 / 8

Now you have the opposite and adjacent sides, just find the hypotenuse with Pythagorean's theorem

15^2 + 8^2 = 289

\sqrt{289} = 17

Now that you have all the sides use the opposite and hypotenuse to get sine and the adjacent and hypotenuse to get cosine then flip to get secant.

sin A = 15/17

cos A = 8/17

sec A = 17/8

What is the slope of the line through the points (2, 4) and (2, -11)?
Shkiper50 [21]

Answer:

The slope of the line would be undefined

Step-by-step explanation:

First you take the y of the second point and subtract it from the y of the first point. -11 - 4. That leaves you with -15. Then you take the x of the second point and subtract it from the x of the first point. that leaves you with 0. Then you put y over x. You then have -1`5/0. That is undefined.
