Answer:
<h2>A = 22.6°</h2><h2>B = 67.4°</h2>
Step-by-step explanation:
Trigonometry:
Use Sine when you have the Opposite and the Hypotenuse.
Use Cos when you have the Adjacent and the Hypotenuse.
Use Tan when you have the Opposite and the Adjacent.
The Opposite is opposite the angle.
The Adjacent is next to the angle
The Hypotenuse is opposite the right angle.
<u>Angle A:</u>
Use Tan when you have the Opposite and the Adjacent.
Tan-1
= 22.6198... ~ 22.6°
<u></u>
<u>Angle B:</u>
Use Tan when you have the Opposite and the Adjacent
Tan-1
= 67.380... ~ 67.4°
22.6° + 67.4° + 90° = 180°
Answer:
1, 5, 15
Step-by-step explanation:
First, I knew 5 was one of them because, 5 was the median and there were only three numbers. Next you have to find out the first and last number. Then, I looked at the mean. To get the mean, you have to add all of the numbers up and divide that by how many numbers there are. Since the mean is 7 and there are 3 numbers, I knew that the sum of all three numbers was 21 because, 21 divided by 3 is 7. Then I saw that the range of all the numbers was 14. The range is the difference between the largest and smallest number so I knew that the largest number subtracted by the smallest number had to be 14. Then, I saw that 15-1=14, and 1+5+15=21. So the three integers are, 1, 5 and 15.
First simplify then solve.
We find there are two solutions. In your case the correct answers are A, C, D
