Find the measure of the indicated angle to the nearest degree.
deff fn [24]

Given:

A right triangle with legs 5 units and 6 units.

To find:

The measure of angle opposite of side whose length is 5 units.

Solution:

In a right angle triangle,

\tan \theta=\dfrac{Opposite}{Adjacent}

Let \theta be the missing angle. Then, for the given triangle,

\tan \theta=\dfrac{5}{6}

\theta=\tan^{-1}\dfrac{5}{6}

\theta=39.805571^\circ

Round the value to the nearest degree.

\theta\approx 40^\circ

Therefore, the measure of the required angle is 40 degrees.

DJ Davon is making a playlist for work; he is trying to decide what 12 songs to play and in what order they should be played. If
Marta_Voda [28]

Answer:

3.63 * 10^19

Step-by-step explanation:

Given that :

Number of choices to select = 12

Category available :

Blues - 14

Country - 25

Disco - 21

To select an equal number of song for each category ; then 4 songs will be selected from each :

Using combination :

(14C4 * 25C4 * 21C4)

Since the order matters for the 12 selected songs ; it thus requires 12 permutation

Thus ;

(14C4 * 25C4 * 21C4) * 12!

nCr = n! / (n-r)!r!

Using calculator;

14C4 = 1001 ;

25C4 = 12650

21C4 = 5985

12! = 479001600

Hence,

(1001 * 12650 * 5985) * 479001600

= 36301596217286400000

=3.63 * 10^19

In this cube, each small square has side length 1 unit.
Nastasia [14]

1. 6 units squared

2. 1 unit cubed

Step-by-step explanation:

In a cube, all the sides of all the squares have the same length.

Therefore, to find the surface area of the cube we will find the area of one square and multiply this with the number of squares in the cube (which is 6 sides)

(1*1) * 6 = 6

= 6 units squared

The formula for volume is Length * Width * Height

1 * 1 * 1 = 1

= 1 unit cubed

What is the length of the hypotenuse
Liula [17]

Answer:

20

Step-by-step explanation:

To find Hypotenuse: Pythagorean Theroem

a^2+ b^2= c^2

The legs are A and B

The side that is directly across from the Right angle is C

12^2 + 16^2 =C^2

144+256=400

400 = c^2

Square root on both sides to get rid of c^2

The square root of 400 is 20

c=20
