Option3 is the answer..!!!

Hello!

Let's review our trigonometric ratios.

Sine= \frac{opposite}{hypotenuse}

Cosine= \frac{adjacent}{hypotenuse}

Tangent=\frac{opposite}{adjacent}

Let's look which lines are opposite, adjacent, and hypotenuse.

Opposite: XZ

Adjacent: YZ

Hypotenuse: XY

Let's plug these into our ratios.

SinY= \frac{XZ}{XY}

CosY=\frac{YZ}{XY}

TanY=\frac{XZ}{YZ}

As you can see, these numbers match answer C.

I hope this helps!

HELP ME!!! ITS DUE TOMMOROW!! Find the largest value of $r$ such that $6r^2+7r+8=6$.
Alex787 [66]
First you need to see that this is a quadratic. I need.to put all of the values on one side of equation to see what I got.
6r^2 + 7r + 8 = 6
6r^2 + 7r + 2 = 0

Now this one is difficult to factor so i will use quadratic equation:
[-b (+-) sqrt (b^2 - 4ac)] / (2a)

we know that a b and c are in a quadratic at these positions.
ax^2 + bx + c

so
[-7 (+-) sqrt (7^2 -(4)(6)(2)] / (2) (6)
[-7 (+-) sqrt (49 - 48)] / 12
[-7 (+-) 1] /12

split into the + and - for 2 answers
(-7 + 1) / 12
-6/12
-1/2

And
(-7 -1) /12
-8 / 12
-2/3

those are.the 2 answers

But but it says largest so -1/2

Give the difference of 8/13​ and 5/13<br><br> A. 3/13<br> B. 8/13<br> C. 5/13
nikitadnepr [17]

Answer:

3/13

Step-by-step explanation:

8/13 subtract by 5/13. If the denominator is the same, you keep it, don't change it. Just subtract the numerator.

Make sure to simplify, if it is already simplified that will be the answer.
