Since it is given that the triangle is a right angle, and one of the other angles is 30 degrees, then we know that this triangle is a 30, 60, 90 triangle. In a 30, 60, 90 triangle, the opposite side of the shortest angle is half of the hypotenuse (which is given as 6). So knowing this, the value of y would be D. 3.

Suppose Jim is going to build a playlist that contains 7 songs. In how many ways can Jim arrange the 7 songs on the playlist?

gulaghasi [49]

Answer:

Jim can arrange the 7 songs on the playlist in 5040 different ways.

Step-by-step explanation:

Given

$Songs = 7$

Required

Ways of arrangement

Since, there is no restriction and conditions.

The songs can be arranged in

$Ways = 7!$

This is so because each song will have a distinct position:

So, we have

$Ways = 7 * 6 * 5 * 4 * 3 * 2 * 1$

$Ways = 5040$
