Suppose ABC is a right triangle with sides a, b, and c and right angle at C. Find the unknown side length using the Pythagorean

Leno4ka [110]

Answer:

a = $\sqrt{7}$

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.:

<em>Suppose ABC is a right triangle with sides a, b, and c and right angle at C. Find the unknown side length using the Pythagorean theorem and then find the values of the six trigonometric functions for angle B. when b=3 and c=4</em>.

My answer:

We will Pythagoras theorem, which states that the sum of squares of two legs of a right triangle is equal to the square of the hypotenuse of right triangle. Because the question says that ABC is a right triangle.

$a^2+b^2=c^2$

Given that: b=3 and c=4

$a^2+3^2=4^2a^2+9=16a^2+9-9=16-9a^2=7$

so a = $\sqrt{7}$

We know that tangent relates opposite side of a right triangle with adjacent side.

$\text{tan}(B)=\frac{a}{b}\\\text{tan}(B)=\frac{\sqrt{7}}{3}$

Which of the following expressions are equivalent to -8/11-3/4-1/4.Choose 3 answers

Effectus [21]

Answer:

option a

option d

option e

Step-by-step explanation:

option a

$-\frac{8}{11}+( -\frac{3}{4})+( -\frac{1}{4})=-\frac{8}{11}-\frac{3}{4} -\frac{1}{4}$

option d

$-(\frac{8}{11}+\frac{3}{4}+\frac{1}{4})=-\frac{8}{11}-\frac{3}{4} -\frac{1}{4}$

option e

$-\frac{8}{11}-(\frac{3}{4}+\frac{1}{4})=-\frac{8}{11}-\frac{3}{4} -\frac{1}{4}$

In Exercises 6 and 7, use the given measure to find the missing value in each data set. 6. The mean of the ages of 5 brothers is

strojnjashka [21]

Solution

Problem 6

For this case we can do this:

12, 16,__, 14, 8, 7

We can solve for x like this:

$\frac{12+16+x+14+8+7}{6}=13$ $x=13\cdot6-(12+16+14+8+7)=21$
