<u>Answer:</u>
The point-slope equation of the line is
or 
<u>Solution:
</u>
Let us assume that the slope is m and the y intercept of the line is b
Hence,
--------- (i)
y intercept means we need to find the value of y when x is 0
Here the line passes through point (4,-6) and slope m = (-2)
Now putting the point (4,-6) in equation (i) we get,





So, the equation of the line will be will be
or 
type cos(155) into a calculator
cos(155)= -0.906307787...
Answer:
X is 45
X-15=30
X=30+15
X=45

i hope that hepled :)
S1/S2 = 1/16
Thus R1/R2 = 1/4
So V1/V2 = 1/64
Answer: 1/64
