Find the sum and enter it in the box below. Enter your answer as a polynomial in descending order, and use the caret (1) for exponents. For example, you would write 4x2 as 4x^2. (2x + 5/6 - 3x2 + 4) + (-16 - 2x5 - 1x2 + 5x)​

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
