Answer:
-3
Step-by-step explanation: Because it is just like saying 6-3
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)
1. Change 1 7/8 to an improper fraction, which gives you 15/8.
2. Use KFC to divide fractions. KEEP the first term, FLIP the second and CHANGE to multiplication.
3. 15/8 x 4/3 = 60/24 = 2 1/2
