Answer:
Step-by-step explanation:
✔️Finding h using trigonometric ratio:
Reference angle = 60°
Opposite = h
Adjacent = 3
Thus:
(tan 60 = √3)
Multiply both sides by 3
✔️Finding c using trigonometric ratio:
Reference angle = 45°
Hypotenuse = 8
Adjacent = c
Thus:
(cos 45 = √2/2)
Multiply both sides by 8
Answer:
59°
Explanation:
If you add the angles 99° from angle C in the top shape and add 22° on the bottom shape it will give you 121°. When you get this subtract it from 180°
180°-121°= 59°
So, it's 58°
You can check by adding 180°+121°+59° = 180°
Answer:
1. 2.9
2. 51 inches
3. (if you can send a picture of the question, I can tell you an answer.
Step-by-step explanation:
for number 1:
You have to add the scores on the left and divide it by the total. What I did was multiply each number on the right with it's pair and added it up. I got 111. Afterwards, I totalled the number of students (I got 38) and divided the scores by the number of students to get 2.9.
for number 2:
You do the same thing as number one but instead of multiplying pairs, you add the heights. I got 255 and then divided it by 5 total heights. I got 51 inches.
for number 3: I didn't get the graph to tell you the answer but I can tell you what everything means.
Symmetric means that both sides of the graph are equal and if you fold the graph in half horizontally, you should get the same shape.
Gaps are where you see blanks in the graph where the data gets cut off and then has stats again.
Cluster is when a huge amount of data is gathered in one area.
Peak is where the data (x-axis) reaches it's highest point (highest y-axis point).

The total number of fish bought was 320. And you know she bought two types of fish. The best way to solve this is guess and check. It would be the fastest. So she bought 7 times as many trigger-fish as parrot fish that means the number of trigger-fish bought was 7p. This means 320 = 7p +p. So all you do is take educated guesses for the number of parrot fish and check if it is right. So if she bought 50 parrot fish. 7(50) + 50 = 400. Close but a bit high. Lets keep guessing. 7(35) + 35 = 245. So now we know the answer is between 50 and 35. So lets try 40. 7(40) + 40 =320. That works so we know she bought 40 parrot fish and 280 trigger-fish.
