Answer:

108

Step-by-step explanation:

Interior angles in a pentagon add up to 540 degrees. So we first need to find the total sum of all the known angles. We do this by calculating 104+108+112=324.

Now we need to find the total sum of the unknown angles, and we do this buy calculating 540-324=216.

The final step is to find the size of one of the 2 remaining angles, and since we know they are equal, we just have to divide by 2. So, 216/2=108. This is our final answer.

Convert from radians to degrees

Natali [406]

Answer:

The answer is

<h2>135°</h2>

Step-by-step explanation:

In order to convert a value from radians to degrees we multiply the value by $\frac{180}{\pi}$

So from the question the value to be converted into degrees is

<h3> $\frac{3}{4} \pi$ </h3>

<u>Converting into degrees we have</u>

<h3> $\frac{3\pi}{4} \times \frac{180}{\pi}$ </h3>

<u>Reduce the expression with π</u>

That's

<h3> $\frac{3 \times 180}{ 4} = \frac{540}{4}$ </h3>

We have the final answer as

<h3>135°</h3>

Hope this helps you

Find the percent of change. Round to the nearest percent.

katovenus [111]

Answer:

<u> -54.5%</u>

Step-by-step explanation:

You will have to use this formula

$\frac{new value-oldvalue}{oldvalue}$

When substituted in you have $\frac{30-66}{66}$

30-66=-36

-36/66= -0.54 (54 repeating)

Then you have to convert this into a percentage, -54.54(repeating) percent

To the nearest hundredth you would round down to<u> -54.5%</u>.

It is a Decrease because it is negatated.
