Suppose u={3,5,6,9,10,13,14,17,19} is the universal set and a={6,10,17}. what does a’ =

Answer

A' = {3 , 5 , 9 , 13 , 14 , 19}

Step-by-step explanation:

∵ U is the universal set

∵ U = (3 , 5 , 6 , 9 , 10 , 13 , 14 , 17 , 19}

∵ A = (6 , 10 , 17}

∵ A' means all elements in the universal set except the elements in A

∴ A' = ( 3 , 5 , 9 , 13 , 14 , 19}

1/2*qr*rs

step-by-step explanation:

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).
