If we know that 2 angles are complements of each other, then they add up to 90 degrees. Knowing this, if we know that the complement of an angle X has an angle value that is 3 times greater, we can write that as such: X + 3X = 90 => 4X = 90. We solve for X to get: 22.5 degrees.

PLEASE HELLPPPP Ms. Rudolph randomly selects one student from a group of students.

Yakvenalex [24]

Using it's concept, it is found that the probability that the selected student is wearing a black shirt is given by:

$p = \frac{n}{n + 15}$

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, we have that out of n + 6 + 9 = n + 15 students, n are wearing black shirts, hence the probability is given by:

$p = \frac{n}{n + 15}$
