In how many ways could you choose two different letters from the letters c, o, u, n, t?
a. 60 ways
b. 20 ways
c. 120 ways
d. 10 ways

Option D is correct.

Step-by-step explanation:

Total number of letters = c , o , u , n , t

We have to find: Numbers of ways in which two letters can be choose.

Combination is used to find numbers of ways.

Number of ways =

Therefore, Option D is correct.

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).
