Does anyone know the answer to this question

lys-0071 [83]

ANSWER

$\cos B = \frac{ \sqrt{3} }{3}$

EXPLANATION

The given triangle is a right triangle.

It was given that,

$a = 1$

and

$b = \sqrt{2}$

Using the Pythagoras Theorem, we can determine the value of c.

${c}^{2} = {( \sqrt{2} )}^{2} + {1}^{2}$

${c}^{2} = 2 + 1$

${c}^{2} = 3$

$c = \sqrt{3}$

The ratio is the adjacent over the hypotenuse.

$\cos B = \frac{1 }{ \sqrt{3} }$

We rationalize to get:

$\cos B = \frac{ \sqrt{3} }{ \sqrt{3} \times \sqrt{3} } = \frac{ \sqrt{3} }{3}$

What is the sum of 9c+(8+3c)?

mixas84 [53]

<span>9c+(8+3c)
9c+8+3c (collect like terms)

9c+3c+8
12c+8

12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:

12c+8 (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)

4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)

</span>
