It can help by giving you the value
That is a 90 degree angle so:
90-22=68
So X=68
To get the y intercept, x must be 0. If x is 0, y would be -8. So, (0,-8) is the y intercept.
Hello!
To solve this you have to add all the values together
A = 5
B = 12
C = 8
D = 10
E = 6
F = 9
5 + 12 + 8 + 10 + 6 + 9 = 50
Then you take the value of D and divide it by the total amount of occurrences
10 / 50 = 1/5 or 20%
The answers is C
Hope this helps!
Answer:
all options are correct.
Step-by-step explanation:
The correct options among all the options are:
- <em>Ancient mathematicians used trigonometry to find angles of triangles.</em>
Trigonometry is used to find the size of a missing side or angle in a right- angled triangle using the sine, cosine or tangent ratios.
- <em>Ancient mathematicians used trigonometry to track the position of the sun.</em>
It is also used in oceanography in calculating the height of tides in oceans.
- <em>Tangent was the first trigonometric relationship used by mathematicians.</em>
The three main functions in trigonometry are Sine, Cosine and Tangent.The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions.
- <em>Cosine was the first trigonometric relationship used by mathematicians.
</em>
- <em>Sine was the first trigonometric relationship used by mathematicians.</em>
