Answer:
40 degrees
Step-by-step explanation:
so, a triangle is 180 degrees. you know that one angle is 60 degrees.
180= 60+ 2x + x
this is the equation of the triangle
120=3x
simplify
40=x
x= 40 degrees
hope this helps :)
The only increasing function is the last option:

<h3>
Which function is increasing?</h3>
Here we only need to see that, is as x increases also do f(x). Then the function will be increasing.
The cases for exponential functions is actually more trivial than that.
- If the base is between zero and 1, then the function is decreasing.
- If the base is larger than 1, then the function is increasing.
In the given options there is only one function with a base larger than 1, which is the last option:

That is the correct option.

r and s are parallel
given ∠4 = ∠5 ( these are congruent interior alternate angles )
between the lines r and s, hence
r and s are parallel lines
