Find the missing side

-2.44

Step-by-step explanation:

Is a right angle triangle

We apply SOHCAHTOA

SOH is sin=Opposite divided by Hypotenuse

CAH is cos=Adjacent divided by Hypotenuse

TOA is tan=Opposite divided by Adjacent

so in this case,cos is the right thing to use

Therefore,x=adjacent

15=Hypotenuse

angle=52°

Cos(52)=x÷15

making x the subject,

x=15cos(52)

x= -2.44

4+4+2x

or

2x+8

step-by-step explanation:

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
