Sum means to Add.
So the sum of d and 9 would be d + 9
Answer:
Step-by-step explanation:
The sum of adjacent angles traversed by a line must equal 180 degrees.
128+x=180
x=52
Answer:
no there can be no such thing to lose legs or those 2 angles added up already are 180 degrees and the 180 has to be split up between 3 angles and if 2 of the angles were 90 degrees the other 2 angles also would be creating a square
Step-by-step explanation:
This is a cubic equation so it will have a total of three roots.
there is only one change of sign so the equation will have one positive real root.
The other 2 roots will be negative and might be real or complex
So, in the list of numbers, 8 and 9 are solutions
