Wnci is having a promotion in which every 42nd caller receives a free concert ticket to jay-z and every 72nd caller receives a backstage access pass. which caller will be the first one to win both?

504th caller

Step-by-step explanation:

To determine who would win both the free concert ticket AND the backstage access pass, we need to find the first number that is divisible by both 42 and 72 at the same time.

That's called the Least Common Multiple (LCM), and it can be found with this formula:

Where gcd is the Greatest Common Divisor, meaning what's the greatest number that divides both numbers without any leftover.

In the case of 42 and 72, the GCD is 6.

So, let's take the formula again, punching in the numbers this time and solving it.

And 504 does divide both 42 (result is 12) and 72 (result is 7).

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

yes
