Trigonometry can be used to determine the height of a cell phone tower by using SOH CAH TOA or the Pythagorean theorem. If you look at it as a right triangle you can figure out how tall the tower is. If an angle is given (not a 90°angle) and the value of a side you can figure out all of the sides on the theoretical right triangle. Including the height of the tower.
Answer:
Yes. No graph paper.
Step-by-step explanation:
Let's say the 3 points are A, B, C.
If A, B and C lie on one line then 
Hence, they lie on one line.
You don't need to use a graph paper to prove it.
Answer:
114
Step-by-step explanation:
since the total degrees of ANY triangle is 180 degrees, you just simply do 180-38-28 and you would get 114!
Assuming the frame is a perfect circle
and 3 inches wide indicates the diameter
area of a circle=pi times radius^2
diameter=2 times radius
radius=1/2 diameter
diameter=3
radius=1/2 times 3
radius=3/2=1.5
area=pi times 1.5^2=2.25
pi is aprox 3.14 so
2.25 times 3.14=7.065 square inches
the answer is 2.25π square inches or 7.065 square inches
