Answer:

<B = 63

AC = 24

AB = 26

Step-by-step explanation:

The total sum of the angles in a right triangle is 180. Knowing this, we can subtract angle A (which is equal to 27), and angle C (which is equal to 90 since it is a right angle).

180 - 90 = 90

90 - 27 = 63

This gives us the answer to the first question, so angle B is equal to 63 degrees.

Now, to find the lengths, we must use sine, cosine, and tangent.

We can use the following formulas to plug in the opposite leg and the angle of A to find the lengths of AB and AC.

$sin(t) = \frac{opposite}{hypotenuse} \\cos(t) = \frac{adjacent}{hypotenuse} \\tan(t) = \frac{opposite}{adjacent}$

Hope this helps!! :]

Which expression gives the distance between the points (4,6)and (7,-3)

amid [387]

The distance between any two points is:

d^2=(x2-x1)^2+(y2-y1)^2 so in this case:

d^2=(7-4)^2+(-3-6)^2

d^2=3^2+9^2

d^2=90

d=√90

d=3√10 units

d≈9.49 units (to nearest hundredth of a unit)

What is the volume of a sphere with a radius of 7 cm? Sphere V = 4 3 πr3 1. Substitute the radius into the formula: V = 4 3 π

netineya [11]

Answer:

1436.75504 or 1372/3π cm^3

Step-by-step explanation:

The volume of a sphere can be found using:

V = 4/3 πr^3

We know the radius is 7, so we can substitute 7 in for r

V = 4/3 π7^3

Evaluate the exponent

V = 4/3 π 343

If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.

v= (4/3*343)π

v=1372/3π

If we want an exact answer, multiply 1372/3 and pi

v=1436.75504

So, the volume is 1436.75504 or 1372/3 π cm^3

What is the mean, median, and standard deviation for the following set of scores: 24, 20, 16, 18, 18, 26, 22? Please show your w

MissTica

Answer:

first: Definitions

mean: the average or the most common value in a collection of numbers

(So u add all numbers and then divide the answer by how much numbers there were)

median: Is middle value.

(example: 4, 5, 6) (The median will be the middle which is 5) (But if there are even amount of numbers like this: 4, 5, 6, 7) (Then you will get the two middle numbers which in this case are 5 and 6 you add them and then divide by 2.)

standard deviation: measures the spread of the data about the mean value

Step-by-step explanation:

Now lets get to problem!

we have numbers:

24, 20, 16, 18, 18, 26, 22

the mean will be: 144 (remember now you have to divide by 7 because there are 7 numbers.)

So it would be 20.57

Now the median:

(Since there are 7 numbers you just find the number in the middle and that would be ur median.)

24, 20, 16, 18, 18, 26, 22

median answer: 18

Like we said: The sample standard deviation measures the spread of a data distribution of the sample. It is usually used to estimate the population standard deviation

So the standard deviation will be: 3.6

I hope this helps :)

Andrei [34K]

Answer:

16 degrees

Step-by-step explanation:

180 degrees = 164 degrees + x,

x = (180 - 164) degrees,

x = 16 degrees
