Suppose that :

A = ( 0 , - 15 )

B = ( 11 , - 4 )

Slope = m = [ y(A) - y(B) ] ÷ [ x(A) - x(B) ]

Now let's juts put the coordinates in the formula to find the slope :

Slope = m = [ - 15 - ( - 4 ) ] ÷ [ 0 - 11 ]

Slope = m = [ - 15 + 4 ] ÷ [ - 11 ]

Slope = m = - 11 ÷ ( - 11 )

Slope = m = 1

A.
5x+12=3x+18
2x+12=18
2x=6
x=3
you would get paid the same amount if you worked 3 hours at each job

B.
5(5)+12
10+12
22

3(5)+18

Find a. Round to the nearest tenth.

Kazeer [188]

Answer:

21.8 cm

Step-by-step explanation:

A useful way to write the Law of Sines relation when solving for side lengths is ...

a/sin(A) = b/sin(B)

Then the solution for 'a' is found by multiplying by sin(A):

a = sin(A)(b/sin(B)) = b·sin(A)/sin(B)

We need to know the angle A. Its value is ...

A = 180° -75° -31.8° = 73.2°

Then the desired length is ...

a = (22 cm)sin(73.2°)/sin(75°) ≈ (22 cm)(0.9573/0.9659)

a ≈ 21.8 cm

_____

I like to use the longest side and largest angle in the equation when those are available. That is why I chose 75° and 22 cm.

If an angle is bisected to form two new 10 degree angles, what was the measure of the original angle?

emmasim [6.3K]

Answer:

20 degrees

Step-by-step explanation:

Bisected means to cut or divide in half. After knowing this you should realize that the two new parts of the angle should be equal. They are both ten degrees, so to get the measure of the original angle add both of the sides together.
