Brian wants to buy a shirt. He can choose an XL, L, M, S, or XS long-sleeve or
short-sleeve in white, black, pink, or blue.
How many choices of combinations does
he have?

40 choices of combinations can be made.

Step-by-step explanation:

Given that Brian wants to buy a shirt, and he can choose an XL, L, M, S, or XS long-sleeve or short-sleeve in white, black, pink, or blue, to determine how many choices of combinations does he have, the following calculation must be performed:

XL + L + M + S + XS = 5

LS + SS = 2

W + B + P + B = 4

5 x 2 x 4 = X

10 x 4 = X

40 = X

Thus, 40 choices of combinations can be made.

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).
