If you are given only the measurements of the three angles of a right triangle, can you find the lengths of the three sides?

erma4kov [3.2K]

Answer:

Because you can't find any of the length if you don't have two other lengths

Step-by-step explanation:

study cosine rule and sine rule

you use cosine rule when you have one angle in-between two length

while you use sine rule when you have two angles and one length

just study cosine rule and sine rule you will understand what am saying

If you plot and connect these points P1(3,2) and P2(6,8) , what figure is Formed? What is the Direction?

Sergio [31]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the points

P1(3, 2)

P2(6, 8)

When we plot P1(3, 2) and P2(6, 8), we determine the line segment P1P2.

The direction of the segment is from P1 to P2.

Determining the length of the segment P1P2.

$\:l=\:\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$=\sqrt{\left(6-3\right)^2+\left(8-2\right)^2}$

$=\sqrt{3^2+6^2}$

$=\sqrt{45}$

$=\sqrt{5}\sqrt{3^2}$

$=3\sqrt{5}$

Thus, the length of the segment is:

$\:\:\:l=3\sqrt{5}$

Determining the equation of a line containing the segment P1P2

Given the points

P1(3, 2)

P2(6, 8)

Finding the slope between P1(3, 2) and P2(6, 8)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(3,\:2\right),\:\left(x_2,\:y_2\right)=\left(6,\:8\right)$

$m=\frac{8-2}{6-3}$

$m=2$

Using the line point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 2 and the point (3, 2)

$y-2=2\left(x-3\right)$

Add 2 to both sides

$y-2+2=2\left(x-3\right)+2$

$y=2x-4$

Thus, the equation of a line containing the line segment P1P2 is:

$y=2x-4$

Help Please !!!(-.-;)y-~~~

Answer:

For employee 1 = 2.5

For employee 2 = 8.6

For employee 3 = 4.4

For employee 4 = 10

For employee 5 = 24

Step-by-step explanation:

number of hour worked= H

total money earned =T

earning per hour =M

we have the following relations:

H =T/M

M =T/H

For employee 1 we have:

T=23.75$

M =9.50$

We calculate H by using the above equations, so we have:

H =23.75/9.50= 2.5

For employee 2 we have:

T=28.38 $

H =3.3

We calculate M by using the above equations, so we have:

M =28.38/3.3 =8.6

For employee 3 we have:

T=38.50$

M =8.75$

We calculate H by using the above equations, so we have:

H =38.50/8.75= 4.4

For employee 4 we have:

T=55 $

H =5.5

We calculate M by using the above equations, so we have:

M =55/5.5=10

For employee 5 we have:

T =60 $

H =2.5

We calculate M by using the above equations, so we have:

M =60/2.5 = 24
