Answer:

C

Step-by-step explanation:

You can use Pythagorean Theorem to find a

c = hypotenuse is the longest side of the right triangle

a² + b² = c²

a² + 24² = 26²

a² = 100

a = 10

<em>Or solving another way,</em>

3-4-5

5-12-13

6-8-10

7-24-25

These are special right triangles.

5 - 12 - 13 => 5x2 - 12x2 - 13x2 => 10 - 24 -26

so, a = 10

Hope this helps ^-^

Answer:

Option C

Step-by-step explanation:

Use the <u>Pythagorean Theorem</u> to find the unknown side.

a^2+b^2=c^2

<h3>We are given that:</h3>
  • b=24
  • c=26

We need to solve for a.

a^2+24^2=26^2\\\\ \text {Solve Exponents:}\\\rightarrow 24^2 = 576\\\rightarrow 26^2 = 676\\\\a^2+576=676\\\rightarrow a^2+576-576=676-576 \text{ (Subtraction Property of Equality)}\\a^2=100\\\sqrt{a^2} =\sqrt{100} \text { (Take the square root on both sides.) }\\\\\boxed {a=100}

<em>Option C should be the correct answer.</em>

If cos Θ = negative 4 over 7, what are the values of sin Θ and tan Θ?
FinnZ [79.3K]
Given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.

A shoe manufacturer collected data regarding men's shoe sizes and found that the distribution of sizes exactly fits the normal c
Lina20 [59]

Answer: 97.72%

Step-by-step explanation:

Given : A shoe manufacturer collected data regarding men's shoe sizes and found that the distribution of sizes exactly fits the normal curve.

Let x be the random variable that represents the shoe sizees.

Also, The population mean = \mu=11 ; Standard deviation: \sigma=1.5

Formula for z:-

z=\dfrac{x-\mu}{\sigma}

Put x= 8, we get

z=\dfrac{8-11}{1.5}=-2

Now, the probability that the male shoe sizes are greater than 8 :-

P(x>8)=P(z>-2)=1-P(z\leq-2)\\\\=1-0.0227501=0.9772499\approx0.9772

Hence, the percent of male shoe sizes are greater than 8 is 97.72%.
