Answer:
Third zero is -1.
Step-by-step explanation:
consider the given polynomial is
It is given that -1 and -3 are two zeroes, therefore (x+1) and (x+3) are two factors of given polynomial.
The given polynomial can be rewritten as
Now, splitting the middle term, we get
Here, power of (x+1) is 2. It means the multiplicity of zero -1 is 2.
So, three zeroes are -1, -1 and -3.
Therefore the third zero is -1.
It's 2/11 because all the others round to 1/2.

Answer:
Q1 is 15
Q2 is 39
Q3 is 51
Q4 is 87
Step-by-step explanation:
The measurement of angle a plus 120 must equal to 180 ( as angles on a straight line must equal to 180)
So measurement of angle a is 60 degrees
Measurement of angle b plus 60 plus 60 must equal to 180
So measurement of angle b is 60
