Find the measure of the missing angle. ​ - 1

Answers

Answer 1
Answer:

X = 159°

Step-by-Step Explanation:

To find the missing angle, you must first find the sum of the interior angles. To do this, you can use the equation:

(n - 2)180

Let n represent the number of sides. This is a regular pentagon, therefore there are 5 sides. Your new equation is:

(5 - 2)180

Once you calculate this, you will find the answer is 540°.

Next, you need to find x. To do this, first add all of your interior angles together. If you didn't know, the square is a right angle, meaning it is 90°.

83 + 90 + 119 + 89 = 381

Now take 540, subtract 381, and your answer is your missing angle (x).

Answers

percent is over a 100 so its 250/100
Step 1: Write down the percent divided by 100.Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 for every number after the decimal point. (For example, if there is one number after the decimal, then use 10, if there are two then use 100)Step 3:Simplify (or reduce) the fraction

What is a 4.16 as a fraction

Answers

We can see that the ".16" takes up two place values after the decimal point this means that it is 16 hundredths or (16)/(100). 4.16 as a fraction can therefore be written as 4(16)/(100) or if you want it simplified, 4(4)/(25).

What is the expanded form of 876 million

Answers

the expanded form is: 800,000,000+70,000,000+ 6,000,000
First lets write 876 million out:- 

876, 000, 000

Now lets write it in expanded form:-

876, 000, 000

800,000,000 + 70,000,000 + 6,000,000 + 0 + 0 + 0 + 0 + 0 + 0  = 876, 000, 000

So, 876 million in expanded form is:-

800,000,000 + 70,000,000 + 6,000,000 + 0 + 0 + 0 + 0 + 0 + 0  =
