(05.02 LC) Given triangle ABC, which equation could be used to find the measure of ∠C?

Mathematics
1 answer:
Sidana [21]3 years ago

Answer:

D. sin m∠C = 2 square root of 5 all over 5

Step-by-step explanation:

The triangle ABC is a right angled triangle. The angle ∠C is where we are asked to find.  The side AB measures 6 , AC measures 3 and the side BC measures 3√5.

The longest side of a right angle triangle is the hypotenuse, that means the side with length  3√5 is the hypotenuse.

Therefore side BC is the hypotenuse side and we are asked to find the angle C. AB is the opposite side while AC is the adjacent side.

Using

sin C = opposite/hypotenuse = 6/3√5 = 2/√5 = 2√5/5

cos C = adjacent/hypotenuse = 3/3√5 = 1/√5

Hi, can you help me answer this question please, thank you!

As your testing H0:p=0.79, then you have a two-tailed test.

The p-value at two-tailed test is given by:

\begin{gathered} p=P(Z\leq-z)+P(Z\ge z) \\ p=P(Z\leq-z)+(1-P(Z\leq z) \\ p=2P(Z\leq-z) \\ 0.79=2P(Z\leq-z) \\ P(Z\leq-z)=\frac{0.79}{2} \\ P(Z\leq-z)=0.395 \end{gathered}

Then, you need to check into the standard normal cumulative table to find at which -z you do have a probability of 0.395. Thus:

As you can see in the picture at z=-0.26 you have a P(Z<=-z)=0.3974

And at z=-0.27 you have a P(Z<=-z)=0.3936.

The average of these values is:

\frac{0.3974+0.3936}{2}=0.3955

Then, you have a probability of 0.395 at a z of:

\frac{-0.26+(-0.27)}{2}=-0.265

Then -z=-0.27, thus z=0.27

Write 10/6 as a mixed number in simplest form
larisa86 [58]
10/6 = 6/6 + 4/6 = 1 + 4/6 = 1 + 2/3

So, the simplest mixed number equaling 10/6 is 1  2/3.

Between which two square roots of integers could you find 2.7182818284
horsena [70]
Well 2.7182818284 is from euler's constant e.

Integers are whole numbers positive and negative. since 2.7182818284 is positive (and you can't take square root of negative number) the integers we find will be positive.

List out square roots.
sqrt1 = 1
sqrt 2 = 1.41
sqrt 3 = 1.73
sqrt 4 = 2
sqrt 5 = 2.2
sqrt 6 = 2.4
sqrt 7 = 2.6
sqrt 8 = 2.8 -----> this is over the constant.

so it's between the square root of 7 and 8

Find an explicit formula for the arithmetic sequence -15, 13, 31, 49
san4es73 [151]

Answer:

No solution (read below)

Step-by-step explanation:

Formula:

a_n = a_1 + (n-1)d

N is the term #

D is the common difference

First, let's find the common difference.

13 - (-15) = 28

Let's see if that checks out.

31-13 = 18

49 - 31 = 18

18 is not equal to 28

Since there is no common difference you cannot find the equation.

Please tell me if you made a typo and comment on my answer, then I can help you find the answer
