What is the value of r?
round your final answer to the nearest whole number.

r = 13

Step-by-step explanation:

Hypotenuse is the side opposite to 90 degree angle, so hypotenuse is r.

Also, with respect to the angle given, the side "12" is the opposite.

So we have opposite side to angle and we need hypotenuse. Which trigonometric ratio related opposite with hypotenuse? It is SINE.

So we can write:

Rounded to nearest whole number, r = 13

r = 13

Step-by-step explanation:

We are given a right angled triangle with one known angle and two side lengths (12 and r) and we are to find the value of r (which is the hypotenuse).

For that, we can use sine.

r ≈ 13

Therefore, the value of r is 13.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
