The sum of interior angles of a polygon with n sides is 180*(n-2)
Therefore, for this question,
n=70
the sum of interior angles=180*(70-2)=180*68=12240 degree
Pls mark me as the Brainliest as I really need it!
Answer:
n = 39
Step-by-step explanation:
The base angles are congruent, that is
3n = 117 ( divide both sides by 3 )
n = 39
Start by converting to like terms, so convert 1/2 to 2/4.
Next, look at the problem. You are adding a negative, which is the same as subtracting, so your new problem looks like this: 2/4 - 3/4.
If you take 3/4 from 2/4, you are left with -1/4. This is your final answer!
