<u>Step-by-step explanation:</u>
Step 1: Given expression:
Step 2: Trying to factor as a Difference of Squares
Factoring
As we know the theory that the difference of two perfect squares, can be factored into (A+B) (A-B)
from this, when analysing, 81 is the square of 9, is the square of
. Hence, we can write the given expression as,
By using the theory, we get
Again, we can further factorise the term
is the square of
. Therefore, it can be expressed as below
Now, we can not factorise further the term . Because it will come as
(3 is not a square term). Thereby concluding that the complete factorisation for the given expression is
Answer:
Mabel would have to draw a new angle that measured 97°.
Step-by-step explanation:
Supplementary angles always add up to 180°.
So, she would have to draw an angle that was °
°
.
So Mabel would have to draw a new angle that measured 97°.
