Measure of angle A=180- Measure of angle C + Measure of angle B
2x=180-(90+3x)
2x=180-90-3x
+3x. +3x
5x=180-90
5/5x=90/5
x=18
Measure of angle is
A= 2x
A=2(18)
A=36

Measure of angle B =
3x
3(18)
54

Simply, Measure of angle A is 36, Measure of angle B is 54 and measure if angle C is 90

PLEASE ANSWER QUICK A manufacturing facility pays its employees an average wage of $4.50 an hour with a standard deviation of 50
evablogger [386]

Answer:

B.77.4%

Step-by-step explanation:

Mean wage (μ) = $4.50

Standard deviation (σ) = $0.50

For nay given salary X, the z-score is given by:

z=\frac{X-\mu}{\sigma}

For X = $3.75, the z-score is:

z=\frac{3.75-4.50}{0.50}\\z=-1.5

For X = $5.00, the z-score is:

z=\frac{5.00-4.50}{0.50}\\z=1

A z-score of -1.5 corresponds to the 6.68th percentile, while a score of 1 corresponds to the 84.13th percentile. Therefore, the percentage of workers getting paid between $3.75 and $5.00 an hour is:

P=84.13-6.68\\P=77.45\%

The answer is alternative B.77.4%

What is the difference between adding and subtracting fractions and multiplying and dividing fractions?
77julia77 [94]
With adding and subtracting fractions, you must find a common denominator. In multiplication, you just multiply numerator by numerator; denominator by denominator. In division, you multiply the fraction by the reciprocal of the 2nd. In multiplication and division, finding a common denominator is not needed.

A student claims that only one operation is needed to calculate the length of the subtended arc when given the measure of a cent
Debora [2.8K]
Having the angle in radians and the diameter of the circle we can easily calculate the length using the following expression

Length = angle(radians)*diameter/2

With this expression we can easily deduce the perimeter of a circle (length of the full arc)

Length = Perimeter = 2*pi*r

There is only one operation involved in this process
