Answer:
its 2u^2-4u+5u-12
Step-by-step explanation:

This result is actually true for any exterior angle. The exterior angle of a triangle is equal to the sum of the two remote angles, and above is a short proof of it.
Answer:
120 degrees! (line) or 300.
Step-by-step explanation:
All lines are 180 degrees, this triangle is congruent, so all sides are 60 degrees. 180 minus 60 is 120.
If it's a measure of a 360 degree angle, using 2 lines from the triangle, then you take 60 away from 360. A circle formed with that angle at it's radius would be 300 degrees.
Answer:
64.96
Step-by-step explanation:
The most common benchmark percents are
and 
We are given
which is closest to
.
Now we calculate
which is equal to
.
We are left with
more to add.
We can say 
Therefore 
Now add the two.

Thus 64.96 is the answer.
