In the problem of insufficient data quantities. I can get a general solution.We know that tangent to a circle is perpendicular to the radius at the point of tangency. It's mean that triangles LJM and LJK are rights.
Let angle JLK like X.
So, angle JLM=61-x.
And it's mean that by using right triangle trigonometry
Radius MJ = LM*cos(61-X)
Find the Least Common Denominator (LCD) which is 28.
-1/4 (7) = -7/28
-3/7 (4) = -12/28
-7 - 12 = -19
-19/28
Simplify if you can.
X = $ 52 for the 12 books Diego bought
B= -42 C= -38
So the difference going up to positive is 4 and the difference going down in negative is -4.
Answer :
$52.50 - x
Step-by-step explanation:
8.75*6 = 52.5
Price of the book = x
$52.50 - x
