Remark
You must use the sin law to find this.
Multiply through by 12
12 * *12
0.5269 = sin(x)
Now you have to use the inverse of the sine function.
Use your calculator for that
2nd F
sin-1
(0.5269)
= 31.79 degrees. <<<<<< Answer.
There sometimes is a second answer. I don't think there is in this case.
You will need 7 because 150 divided by 20 is 7
Answer:
6x² (2x - 5)
Step-by-step explanation:
12x³ - 30x²
= 6x² (2x - 5)
Answer:
15 and 5 hours.
Step-by-step explanation:
Call x the time taken by the first chap, and y the second.
Let's divide by 5 and play with the LHS of the first equation a bit:
we know how much x+y is ( first equation!) let's solve.
At this point it's easy to check that 
y = -4x
y = mx+b
b = 0
m = -4
here are some basic directions:
1. mark the point (0, 0) on the coordinate plane since b, aka the x intercept (where the line intersects with the x axis)
2. mark another point (1, -4) on the coordinate plane since we have defined a hawt slope ykyk
3. use the two points to guide ur ruler and draw a line idk how to describe it but yeah <3
