Triangle not drawn to scale

Answer:

b = 23.3

Step-by-step explanation:

First, we need to determine whether this is a right or non-right triangle.

We know that the sum of all the angles in a triangle must add up to 180, so we can add angles A and B and subtract the sum from 180:

$180-(40+88)=180-128=52$

The 52 indicates that it is a non-right triangle, so we must rely on either the law of sines or law of cosines to find the measure of b.

Given that we have angle A and its resulting side, a, along with angle B, we can use the law of sines:

$\frac{sin A}{a}=\frac{sin B}{b}$

$\frac{sin 40}{15}=\frac{sin 88}{b}\\ \\ 15*sin 88=b * sin 40\\\\b=\frac{b*sin 40}{sin 88}\\ \\b=23.3216=23.3$

How many different ways can the students at a school select the president, vice president and secretary from a group of 5?

sattari [20]

Answer: 60 ways.
Explanation: Suppose that we had 5 people, A, B, C, D, and E, and we had to select a P, VP, and S.

For the President, we have 5 different selections.
If we choose a president, then we can only pick 1 from 4 people for the VP.
Using the same logic, we'd have 3 different choices for the S.

Hence, we have 5 · 4 · 3 different ways.

Alternatively, this is:

$\frac{5!}{(5 - 3)!} = ^{5}P_3$ different ways.
