The domain (input values) of the cosine function is all negative and positive angle measures.
Let the function be f(x) = cos(x)
The domain of cos(x) is -∞ < x < ∞
The range is -1 ≤ f(x) ≤ 1
Hence, domain of cos(x) is all (+) and (-) angle measures.
Same goes with sine function as well
For function f(x) = sin(x)
The domain is -∞ < x < ∞ and range -1 ≤ f(x) ≤ 1
However for f(x) = tan(x) the same is not applicable.
90,000 since you are rounding the whole number to ten thousand 90,000 is more closer than 80000. you have to round to the number it's asking so the rest of your answer after ten thousand should be left zero. therefore making the answer 90,000.
Angle 1: 33, Angle 2: 147
Step-by-step explanation:
If I have angle x, and its supplement angle is 3 times its supplement increased by 48 degrees, then I know the following:
Angle 1 = x
Angle 2 = 3x+48
Both of these angles add to 180 degrees.
x+(3x+48)=180
= 4x+48=180
=4x=132
=x=33, Angle 1 = 33 degrees
So angle 1 is 33 degrees
that should mean that angle 2 is 147
