Find sin0, cos0, tan0

djverab [1.8K]

Answer:

sin(θ) = 12/13, cos(θ) = 5/13, tan(θ) = 12/5

Step-by-step explanation:

We need to find sine, cosine, and tangent of theta for this triangle.

First, define the different trigonometric functions:

- sine is opposite side to the angle divided by the hypotenuse (longest side not adjacent to the 90 degree angle)

- cosine is the adjacent side next to the angle divided by the hypotenuse

- tangent is the opposite side to the angle divided by the adjacent side

Now, look at theta (θ):

- the opposite side is marked 12

- the adjacent side is marked 5

- the hypotenuse is marked 13

So:

- sin(θ) = opposite / hypotenuse = 12/13

- cos(θ) = adjacent / hypotenuse = 5/13

- tan(θ) = opposite / adjacent = 12/5

Thus the answers are: sin(θ) = 12/13, cos(θ) = 5/13, tan(θ) = 12/5.

Please help im stuck on this question

VARVARA [1.3K]

Answer:

(12,0)

Step-by-step explanation:

slope m=

$\frac{54-36}{27-22} =\frac{18}{5}$

$y-36=\frac{18}{5}(x-22)\\\\5y-180=18x-396\\\\y=\frac{18x}{5} -\frac{46}{5}$

$0=\frac{10}{5}x-\frac{46}{5}\\\\x=\frac{216}{18} =12$

hope it helps...

have a great day

Answer:

0.006 is the probability that the record will be broken in next year.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 62 seconds

Standard Deviation, σ = 0.8 seconds

We are given that the distribution of face time is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

The record will be broken if the time is less than 60 seconds.

P(time is less than 60 seconds)

P(x < 60)

$P( x < 60) = P( z < \displaystyle\frac{60 - 62}{0.8}) = P(z < -2.5)$

Calculation the value from standard normal z table, we have,

$P(x < 60) =0.006 = 0.6\%$

Thus, 0.006 is the probability that the record will be broken in next year.
