Answer:
Step-by-step explanation:
So an angle has two parts. Initial side and terminal side.
Inital side like on x axis. and terminal side shows how much it open up. Here the terminal angle terminates in second quadrant so we have the following
- A negative Cosine Value
- A positive Sine value
- A negative Tangent Value.
Now, using Pythagoras identity let solve for cos theta.
Here you on the right track but remeber that son theta=1/3 so sin theta squared would be 1/3 squared so we have
Note since cosine is negative in second quadrant, cos theta is
To find tan theta we do the following
So
Tan is negative in second quadrant
Answer:Since x-intercepts just where the line touches the x-axis, you only need to find the coordinate of that point, which is (8,0) in (x,y) coordinate format.
Answer:
677
Step-by-step explanation:
the sequence is 1, 2, 5, 26, 677
the first term is 1
to find the 2nd term, do:
3rd:
4th:
5th:
V = whl
66 = 2.2 x 5 x w
66 = 11w
w = 66/11
w = 6
answer: width = 6 ft
