Divide the percentage by 100. EXAMPLE: 50% = 0.5
Cos=adjacent/hypotenuse
Cos30=x/20
x=cos30 *20
Sorry I don’t have a calculator right now
equation in slope-intercept form is:

Step-by-step explanation:
The general form of slope-intercept form is:

where m is the slope and b is the y-intercept
In the question we are given slope m=9 and a point(0,7)
We will find b i.e y-intercept

So, value of b=7 and value of slope m=9
So, equation in slope-intercept form is:
