Answer:

54 Degrees

Step-by-step explanation:

We know that a triangle has to have 180 degrees in all. we also know that the bottom lines is a straight angle, so 180 degrees.

using this information, we can find n. We know that n+78 is 180, so n=102

We also know that o+102+24=180, so

o=54

Hope this helps!

I need helpppp (10 points )

Answer: The flagpole is about 22.3 feet tall.

This is roughly the size of a two story building, assuming each floor is 10 feet or so.

Since this height is under 25 ft, this flagpole is in compliance with the regulation.

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

Work Shown:

The horizontal leg of the triangle is 36 ft. This is the adjacent leg to the reference angle 25 degrees.

The vertical leg of the triangle is x-5.5, and this leg is the opposite side to the reference angle 25 degrees.

Use the tangent rule to connect the opposite and adjacent sides.

Solve for x.

tan(angle) = opposite/adjacent

tan(25) = (x-5.5)/36

36*tan(25) = x-5.5

x-5.5 = 36*tan(25)

x = 36*tan(25)+5.5

x = 22.28707569358

x = 22.3 ft is the approximate height of the flagpole

Make sure your calculator is in degree mode.

The height is not over 25 ft, so this flagpole meets the requirements.

Which of the following is located over the center of the base of a regular pyramid

kenny6666 [7]

Vertex is located over the center of the base of a regular pyramid.

<h3>What is Vertex Angle?</h3>

Vertex angle is defined as the angle formed by two lines or rays that intersect at a point. These two rays make the sides of the angle.

Here, Vertex is the point which is located over the center of the base of a regular pyramid.

There are two college entrance exams that are often taken by students, Exam A and Exam B. The composite score on Exam A is appro

elena55 [62]

Answer:

B.The score on Exam A is better, because the percentile for the Exam A score is higher.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

Two exams. The exam that you did score better is the one in which you had a higher zscore.

The composite score on Exam A is approximately normally distributed with mean 20.1 and standard deviation 5.1.

This means that $\mu = 20.1, \sigma = 5.1$ .

You scored 24 on Exam A. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{24 - 20.1}{5.1}$

$Z = 0.76$

The composite score on Exam B is approximately normally distributed with mean 1031 and standard deviation 215.

This means that $\mu = 1031, \sigma = 215$ .

You scored 1167 on Exam B, s:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{1167 - 1031}{215}$

$Z = 0.632$

You had a better Z-score on exam A, so you did better on that exam.

The correct answer is:

B.The score on Exam A is better, because the percentile for the Exam A score is higher.

Please solve these four equations a) x/3=x+4 b) m-3=4/5m-2 c) x/5-4=2-2x/5 d) 1/2+w=8-3w/2

Ilia_Sergeevich [38]

I hope these help you

A)

x3=x+4Step 1: Simplify both sides of the equation.13x=x+4Step 2: Subtract x from both sides.13x−x=x+4−x−23x=4Step 3: Multiply both sides by 3/(-2).(3−2)*(−23x)=(3−2)*(4)x=−6Answer:x=−6

B)

m−3=45m−2Step 1: Subtract 4/5m from both sides.m−3−45m=45m−2−45m15m−3=−2Step 2: Add 3 to both sides.15m−3+3=−2+315m=1Step 3: Multiply both sides by 5.5*(15m)=(5)*(1)m=5Answer:m=5

C)

x5−4=2−2(x5)Step 1: Simplify both sides of the equation.x5−4=2−2(x5) Simplify: (Show steps) 15x−4=−25x+2Step 2: Add 2/5x to both sides.15x−4+25x=−25x+2+25x35x−4=2Step 3: Add 4 to both sides.35x−4+4=2+435x=6Step 4: Multiply both sides by 5/3.(53)*(35x)=(53)*(6)x=10Answer:x=10

D)

12+w=8−3(w2)Step 1: Simplify both sides of the equation.12+w=8−3(w2) Simplify: (Show steps) w+12=−32w+8Step 2: Add 3/2w to both sides.w+12+32w=−32w+8+32w52w+12=8Step 3: Subtract 1/2 from both sides.52w+12−12=8−1252w=152Step 4: Multiply both sides by 2/5.(25)*(52w)=(25)*(152)w=3Answer:w=3
