Answer:
57.8º
Step-by-step explanation:
According to the law of sines [tex]\frac{sinA}{a}[/tex] = [tex]\frac{sinb}{b}[/tex] = [tex]\frac{sinc}{c}[/tex].
In this triangle we have two sides with two of their angles.
Let's make 8 cm side a with 38º as its angle, and 11 cm side b with x as its angle.
[tex]\frac{sinx}{11}[/tex] = [tex]\frac{sin38}{8}[/tex]
Now we multiply both sides by 11 to get rid of the denominator on the left.
sinx = [tex]\frac{11sin38}{8}[/tex]
To find x, we use inverse sine.
x = sin⁻¹ (11sin38/8)
Plug this into a calculator, and you will get 57.837.
Round this to 57.8º
Hope this helps!

how do you know you have a direct variation in the relationship between two quantities?
Answers
“Say you have y=2x. That is a direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2d to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.”

Equation parallel to y = 3x + 2 and passing through (1, 1)
Answers
Answer:
y = 3x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, then
y = 3x + c ← is the partial equation
To find c substitute (1, 1) into the partial equation
1 = 3 + c ⇒ c = 1 - 3 = - 2
y = 3x - 2 ← equation of line

What is an equation of the line that passes through the points (2, 2) and (-2, 8)?
Answers
Answer:
y = −1.5x + 5
Step-by-step explanation:
x y
2 2
-2 8
From 2 to 8, we need to add 6 ( y section)
From 2 to -2, we need to subtract 4 (x section)
Now we need to do y/x
so...y/x = -6/4 = -3/2 = - 1.5
And thats how we find our slope.
To find the y-intercept I just used a graph in order to find it.....

A school band raised $252 by holding a car wash. The band
washed 42 cars in all. Which equation can be used to find n,
the average amount they earned per car?
Answers
The equation that can be used to find the average amount they earned per car is 42n = 252 and they earned $6 per car.
Given that a school band raised $252 by holding a car wash, they washed 42 cars in all.
We need to determine the equation that can be used to find n, the average amount they earned per car.
To find the average amount earned per car (n), you can use the equation:
n = Total amount raised / Total number of cars washed
In this case, the total amount raised is $252, and the total number of cars washed is 42.
So the equation to find n would be:
42n = 252
n = 252 / 42
Now, you can calculate n:
n = 6
Therefore, the average amount they earned per car is $6.

Nora is a teacher and takes home 31 papers to grade over the weekend. She can grade at a rate of 6 papers per hour. How many papers would Nora have remaining to grade after working for 5 hours? ( show work )
Answers
Answer:
Nora would have 30 papers graded in 5 hours.
Step-by-step explanation:
6 papers per hour x 5 hours = 30 papers graded in 5 hours
Answer:
Nora will have 1 page left to grade after working for 5 hours.
Step-by-step explanation:
Her constant is 6 papers per hour.
After 5 hours, she would grade 5x6 papers, which is 30 papers.
So we know she is going to grade 31 papers, and she has already done 30.
So 31-30=1, that means that she has 1 more paper left to grade.
