Answer:
measure angle OML = 26°

Explanation:
Let's consider the two triangles OML and OMN, we have:
measure angle MOL = measure angle MON
ON = OL
OM is a common sides

Therefore, based on SAS (side-angle-side):
ΔOML is congruent to ΔOMN

From this congruency, we have:
measure angle L = measure angle N
9x - 8 = 7x + 8
9x - 7x = 8 + 8
2x = 16
x = 8

Therefore:
measure angle L = 9(8) - 8 = 64°
measure angle N = 7(8) + 8 = 64°

Now, in triangle OML, we have:
angle NOM is an exterior angle of the triangle. This means that its measure is equal to the summation of the other two non-adjacent angles.
This means that:
measure angle NOM = measure angle L + measure angle OML
90 = 64 + measure angle OML
measure angle OML = 90 - 64 = 26°

Hope this helps :)

melomori [17]

First: markup rate × wholesale price = amount of markup

Second: Well the markup rate is a percentage, you have to convert it into a decimal. Percent means "out of one hundred," so <span>80%</span> is equivalent to <span>80/100 </span>which is also equal to <span>80÷100</span>.

<span>Third: 80÷100=0.80</span>

0.80 × $93.00 = $74.40

Fourth: The markup rate is a percentage of the wholesale price that is added to get the retail price, you can find the retail price with the following equation: amount of markup + wholesale price = retail price

<span>$74.40</span> + <span>$93.00</span> = <span>$167.40</span>

The retail price of the chair should be <span>$167.40</span>.

14. Find the distance between (7,217pi/180 ) and (5,-23pi/36 ) on the polar plane.
irina [24]

Answer: the distance is  3.49 units

Step-by-step explanation:

There are some ways to find the exact distance, i will calculate the distance in rectangular coordinates.

When we have a point (R, θ) in polar coordinates, we can transform it into rectangular coordinates as:

x = R*cos(θ)

y = R*sin(θ)

Then we have:

(7,217pi/180 )

R = 7

θ = (217/180)*pi

x = 7*cos( (217/180)*pi) = -5.59

y = 7*sin( (217/180)*pi) = -4.21

So this point is (-5.59, -4.21) in rectangular coordinates.

And the other point is  (5,-23pi/36 )

R = 5

θ = -(23/36)*pi

x = 5*cos(  -(23/36)*pi ) = -2.11

y = 5*sin(  -(23/36)*pi ) = -4.53

So this point is (-2.11, - 4.53)

Then the point distance between those points is:

D = I (-2.11, -4.53) - (-5.59, -4.21) I

D = I (-2.11 + 5.59, -4.53 + 4.21) I

D = I (3.48, -0.32) I = √( (3.48)^2 + (-0.32)^2) =  3.49

Which graph correctly solves the system of equations below? <br> y=-x^2+1 <br> y=x^2-4
KIM [24]
Red line shows
y=x^2-4 , cause it's going through point (0,-4)

So blue line shows
y= -x^2+1 Point (1,0) belong to it , moreover x factor is negative , so the arms of parabola will go down

Have nice evenig :)
