Answer:
63 degrees
Step-by-step explanation:
All angles of a triangle always add up to 180 degrees.
So you take both angles and add them together-55+72=117
You then would take 180 and subtract the total- 180-117=63
And that would be your final answer
Sum of 3 angles in a triangle=180
x+55+72= 180
x+ 127=180
x= 180-127
x= 53

Step-by-step explanation: Ok so it is backwerd to pas would be nagitv
First you must know that is i∧2= -1
x∧3-4x∧2+4x-16 = x∧2 (x-4) + 4 (x-4) = (x-4) (x∧2+4) = (x-4) (x∧2-(-4)) =
= (x-4) (x∧2-(-1) *4) = (x-4) (x∧2- i∧2*2∧2) = (x-4) (x∧2-(2i)∧2) = (x-4) (x-2i) (x+2i)
Good luck!!!
