8 0

Answer:

Part A) sin(A)=\frac{2\sqrt{42}}{23}

Part B) cos(A)=\frac{19}{23}

Part C) tan(A)=\frac{2\sqrt{42}}{19}

Step-by-step explanation:

Part A) we know that

In the right triangle ABC of the figure the sine of angle A is equal to divide the opposite side angle A by the hypotenuse

so

sin(A)=\frac{BC}{AB}

substitute the values

sin(A)=\frac{2\sqrt{42}}{23}

Part B) we know that

In the right triangle ABC of the figure the cosine of angle A is equal to divide the adjacent side angle A by the hypotenuse

so

cos(A)=\frac{AC}{AB}

substitute the values

cos(A)=\frac{19}{23}

Part C) we know that

In the right triangle ABC of the figure the tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A

so

tan(A)=\frac{BC}{AC}

substitute the values

tan(A)=\frac{2\sqrt{42}}{19}

Angelique throws a different six-sided dice 120 times.
Alja [10]

The experimental probability of getting a multiple of 3 is \frac{3}{8}.

Given that, Angelique throws a different six-sided dice 120 times.

<h3>What is Probability in maths?</h3>

Probability denotes the possibility of something happening. It's a field of mathematics that studies the probability of a random event occurring. From 0 to 1, the value is expressed. Probability is a mathematical concept that predicts how likely occurrences are to occur.

We know that, Probability  of an  event=\frac{Number  of favourable  outcomes}{Total number  of outcomes}

Number of favourable outcomes =21+24=45

Total number of outcomes = 120

Probability of getting a multiple of 3=\frac{45}{120} =\frac{3}{8}

Therefore, the probability of getting a multiple of 3 is \frac{3}{8}.

5(x - 3) = 2(x + 6) + 3x
Verdich [7]
The first one is
5x-15=2x+12+3x
5x-2x-3x=12+15
0=27

The second one is
6.5x-7.75x=-12+14.5
-1.25x=-2.5
Divide both sides by - 1.25
X=. 02

The third one is
K-10=3
K=13
The second part of the third one is
-|k-10|=3
-k+10=3
-k=3+10
-k=13
Divide both sides by negative
K=-13

The fourth one is
4n+32=56
4n=56-32
4n=24
Divide both sides by 4
N=6
The second part to that one is
-4|n+8|=56
-4n-32=56
-4n=88
Divide both sides by - 4
N=22

The fifth one is
N+7-6=8
N=8-7+6
N=1+6
N=7
The second part to this one is
-|n+7|-6=8
-n-7-6=8
-n=8+7+6
-n=21
Divide both sides by negative
N=-21

The last one is
5x-7-3=9
5x=9+7+3
5x=19
Divide both sides by 5
X=19 over 5
The second part to this one is
-|5x-7|-3=9
-5x+7-3=9
-5x=9-7+3
-5x=5
Divide both sides by - 5
X=-1
I hope this helps you out.
