Initially, three rms A, B, and C share the market for a certain commodity. Firm A has 20% of the market, Firm B has 60%, and C has 20%. In the course of the next year, the following changes occur: A keeps 85% of its costumers, while losing 5% to B and 10% to C. B keeps 55% of its customers, while losing 10% to A and 35% to C. C keeps 85% of its customers, while losing 10% to A and 5% to B. Write the transition matrix and using matrix multiplication nd the market share (how many customers) of each company after one year.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
