Answer:

\tan(22.6)=\frac{a}{12}

Step-by-step explanation:

We know that \cos(22.6)=\frac{b}{13}. Rounding the value of b as asked in the problem gives b=12.

From the right-triangle definition of cosine, b must be the adjacent side to the angle 22.6º and the hypothenuse of the triangle must be 3.

Then, a is the opposite side of the angle 22.6º therefore using the definition of sine, \sin(22.6)=\frac{a}{3}. Solving for a, we obtain a=3 sin(22.6)=3\cos(22.6)\tan(22.6)=b\tan (22.6)=12\tan(22.6).

We conclude that \tan(22.6)=\frac{a}{12}.

What is the slope of the line that passes through the points E(5,1)and F(2, -7)
Lelechka [254]
Use slope formula y^2-y^1/x^2-x^1
So.
(-7-1)/(2-5) = -8/-3 = 8/3

PLEASE HELP ME!!! Point Q is located at (-4, 6) Point R is located at (8, 6)
HACTEHA [7]
Q = (-4, 6)
R = (8, 6)

You can work out the distance between the points by doing the following formula:


√(x₂ - x₁)² + (y₂ - y₁)²

Factor in our points:

√(8 - -4)² + (6 - 6)²

Solve the brackets (remember a negative and a negative make a positive):

√(12)² + (0)²

= √144 + 0

= √144

Solve this expression to get your final answer of the distance between two points:

√144 = 12

I hope this helps. If it does then a Thanks or a Brainliest would mean a lot! :)
