Answer:
Step-by-step explanation:1
The equation of the line is
4b + a = 0
The slope of the line is
m = -1/4
With a rise of 1 and run of -4 which corresponds to a hypotenuse of
√(4² + (-1)²) = √17
Therefore, the sine of the angle is
sin θ = 1/√17<span />
To figure out the number we need to set up our equation to make more sense.
<u>3/5 = 30/x</u> (x is our missing number)
We know that what ever you do to the top of the fraction you can do to the bottom.
So if we multiply 3 x 10 we get 30.
Therefore to get the number we must multiply 5 by 10
5 x 10 = 50
So our answer and missing number is 50
The expression is x=3 * 4. x=12
I mean im prob in a lower grade then you so i'd say b?
