Answer:

Measure of angle b is 42 degrees

Step-by-step explanation:

Since angle b is part of a right angle, we can see that part of the right and blue is 48 degrees, and the other part is b. So, we can do 90-48 to get 42 degrees.

Find the approximate perimeter of quadrilateral PYRO plotted below round your final answer to the nearest hundredth

polet [3.4K]

Answer:

<h2>The perimeter of the figure is 46.3 units, approximately.</h2>

Step-by-step explanation:

To find the perimeter of this figure, we need to use the formula

$d=\sqrt{(y_{2} -y_{1} )^{2} +(x_{2}-x_{1} )^{2} }$ , which gives the distance between two points.

<h3 /><h3>Distance of PO.</h3>

$P(-3,2)$ and $O(0,-6)$ .

Using the formula, we have

$d_{PO}=\sqrt{(-6-2)^{2}+(0-(-3))^{2} } =\sqrt{(-8)^{2}+(3)^{2} }\\ d_{PO}=\sqrt{64+9}=\sqrt{73} \approx 8.5$

The distance from P to O is around 8.5 units.

<h3>Distance of PY.</h3>

$P(-3,2)$ and $Y(6,-2)$ .

$d_{PY} =\sqrt{(-2-2)^{2}+(6-(-3))^{2} }=\sqrt{(-4)^{2}+(9)^{2}} =\sqrt{16+81}\\ d_{PY} =\sqrt{97} \approx 9.8$

The distance from P to Y is around 9.8 units.

<h3>Distance of YR.</h3>

$Y(6,-2)$ and $R(3,-6)$

$d_{YR} =\sqrt{(-6-(-2))^{2}+(3-6)^{2} }=\sqrt{(-4)^{2}+(-3)^{2}} =\sqrt{16+9}\\ d_{PY} =\sqrt{25} = 5$

The distance from Y to R is 25 units.

<h3>Distance of OR.</h3>

This is an horizontal side, we don't need to use the formula. The distance from O to R is 3 units.

Now, the perimeter is the sum of all sides.

$P \approx 8.5+9.8+25+3 \approx 46.3$

Therefore, the perimeter of the figure is 46.3 units, approximately.

Write an expression using fractions to show how to determine the amount that each person will pay. Then calculate each person's

DiKsa [7]

The fraction based on the information given illustrated for each person.

<h3>How to illustrate the information?</h3>

Me: $14.89

Friend 1: $7.27

Friend 2: $25.67

Friend 3: $11.59

Total = $59.42

The fraction for each person will be:

Me: $14.89 = 14.89/59.42 = 0.25

Friend 1: $7.27 = 7.27/59.42 = 0.12

Friend 2: $25.67 = 25.67/59.42 = 0.32

Friend 3: $11.59 = 11.59/59.42 = 0.195
