Answer:
x = 73.17
Step-by-step explanation:
To solve this problem we are going to have to use trig function
The three main trig functions are
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Hypotenuse
( where hypotenuse = longest length , opposite = side length opposite of angle and adjacent = other side length )
Here, we are given two side lengths and we want to find an angle.
We are given the hypotenuse and its adjacent ( we know this because we are not given its opposite )
When you have the adjacent and hypotenuse you use cosine.
So we have Cos"x" = adj / hyp
adj = 22 and hyp = 76
So Cos"x" = 22/76
==> take the inverse of cos to both sides
x = 73.17 ( rounded to the nearest hundredth )
and we are done!
The energy usage of a light bulb is a function.
The input for the function is <u>time</u> measured in hours.
The output of the function is energy usage, measured in Kilo watts.
<u>E</u> (energy) is a function of <u>t</u> (time).
The graph of the function will show energy usage on the <u>y</u> axis and time on the <u>x</u> axis.
If you have a maybe text book look in there it may give you the answer
Answer:
No.
Step-by-step explanation:
The triangle inequality theorem states that the sum of two sides of a triangle must be greater than the third side.
5 + 8 = 13.
13, which is the sum of two sides, is not larger than 16, the third side.
Therefore, a triangle cannot have these side lengths.
The answer to this question is 240
