Find the measure for < LQR

Answers

Answer 1

Answer:

Step-by-step explanation:

90 - 12b = - 3b + 63

- 12b + 3b = 63 - 90

- 9b = - 27

- b = - 27/9

-b = -3

b = 3

to find the measure of MQR:

-3*3 + 63 = 54°

to find the measure of LQR:

180 - 54 = 126° + 1 = 127°

Answer 2

Answer: 131 degrees

====================================================

Work Shown:

Angles MQX and LQR are vertical angles, so they are equal to one another.

angle MQX = angle LQR

-4a+139 = 4a+123

-4a-4a = 123-139

-8a = -16

a = -16/(-8)

a = 2

Use this to find each angle

angle MQX = -4a+139 = -4*2+139 = 131angle LQR = 4a+123 = 4*2+123 = 131

We get the same value 131 each time, so this confirms we have the correct value for 'a', and it confirms our answer for angle LQR.

find sin θ and cos θ if tan θ= 1/4 and sin 0>0.

Answers

Answer:

[tex]\displaystyle \sin(\theta)= \frac{\sqrt{17}}{17}[/tex]

[tex]\displaystyle \cos(\theta)= \frac{4 \sqrt {17} }{ 17 }[/tex]

Step-by-step explanation:

We want to find sin(θ) and cos(θ) given that tan(θ) = 1/4 and sin(θ) > 0.

First, since tan(θ) and sin(θ) are both positive, cos(θ) must be positive as well.

Recall that tangent is the ratio of the opposite side to the adjacent side.

Therefore, the hypotenuse is:

[tex]h=\sqrt{4^2+1^2}=\sqrt{16+1}=\sqrt{17}[/tex]

So, with respect to θ, the opposite side is 1, the adjacent is 4, and the hypotenuse is √17.

Then it follows that:

[tex]\displaystyle \sin(\theta)=\frac{1}{\sqrt{17}} = \frac{\sqrt{17}}{17}[/tex]

And that:

[tex]\displaystyle \cos(\theta)= \frac{4}{\sqrt{17}} = \frac{4 \sqrt {17} }{ 17 }[/tex]

Solve for T

t =

Answers

Answer:

t=-4

Step-by-step explanation:

48/-12

Answer:

48=-12t

We simplify the equation to the form, which is simple to understand

48=-12t

We move all terms containing t to the left and all other terms to the right.

+12t=-48

We simplify left and right side of the equation.

+12t=-48

We divide both sides of the equation by 012 to get t.

t=-4

Answers

Answer:

v < 9

Step-by-step explanation:

Since the value of the hat is less than 9, we will use a less than sign.

In the inequality, the less than sign has to be in front of 9.

So, put this together:

For the following sample of n 5 10 scores:
a. Assume that the scores are measurements of a discrete variable and find the median.
b. Assume that the scores are measurements of a continuous variable and find the median by locating the precise midpoint of the distribution.
Scores: 2, 3, 4, 4, 5, 5, 5, 6, 6, 7

Answers

Answer:

Step-by-step explanation:

Given that:

scores = 2, 3, 4, 4, 5, 5, 5, 6, 6, 7

Since the scores are already in ascending order; then the median which is the middle number will be:

median = (5th term + 6 term)/2

median = (5+5)/2

median = 10/2

meian = 5

Use the cumulative percentage table

6 2 9 90%

7 1 10 100%

fraction = the no. required to reach 50%/ no. in that interval

= 1/3
