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:
R= 20.88 ft
Step-by-step explanation:
See the diagram attached, this satisfies the condition, ΔKLM is enclosed in a circle of radius R.
LN=16 ft (given)
The value of KM is 2R because as the ∠KLM forms an angle of 90°, therefore, the line KM passes through the center.
Area of a triangle =
Now let's find he area of the ΔKLM=
=
Also the area can be found out by =( As KLM is a right angled triangle)
KL= KM cos 25°= 2R cos 25°
LM= KM cos 55°= 2R sin 25°
Area= x 2R cos 25°x 2R sin 25 °
= sin 50°
sin 50°= 16R
R sin 50°=16
R= 20.88 ft
The slope is 2 when simiplified.
Its really Simple math~

Answer: (x - 2y) + 3
Step-by-step explanation: The quantity x minus 2y is (x - 2y), then we add 3.
