Answer:

cos(m∠B) = 2√5/5

Step-by-step explanation:

Easiest way is to guess and check on this problem. When you take the cos(m∠B), you would get 6/3√5, rationalized to 2√5/5. That would be the correct answer.

Answer:

Option 1

Step-by-step explanation:

Cos B = \frac{adjacent}{hypotenuse}

<u><em>Where adjacent = 6, Hypotenuse = 3√5</em></u>

Cos B = \frac{6}{3\sqrt{5} }

Cos B = \frac{2}{\sqrt{5} }

Cos B = \frac{2\sqrt{5} }{5}

Step-by-step explanation:

Well, to make things easier, we can first note that 24/4 is equal to 6. This helps because integers are easier to work with compared to fractions. Next, multiplying 2 by 6, we get 12.

What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?
AnnZ [28]

The value of n in given proportion is 16

<u><em>Solution:</em></u>

We have to find the value of "n" in the proportion

<em><u>Given proportion is:</u></em>

<em><u></u></em>\frac{n}{28} = \frac{4}{7}<em><u></u></em>

We can solve the above proportion by cross-multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

->\frac{n}{28} = \frac{4}{7}

-> 7 *  n = 4 * 28

-> n = \frac{4 * 28}{7}

-> n = 4 * 4 = 16

Thus the value of n in given proportion is 16
