Answer:
x = 63
Step-by-step explanation:
It's Quadrilateral so:
360-90-72= x + x +22 (Cause that 2 triangle is isosceles)
2x=126
x=63
I think 12 minutes because if you take 9 divide it by 3/4 you get 12
The first quadrant ..........
The answer is B because you have to find f(x) which is the height of the diver & that's what you would need to find out
Answer:

Step-by-step explanation:
Here we are going to apply the rule of "Square of the difference". The rule is as given below
---------(A)
Now we have our original polynomial as

Which can be re written as
---------------(B)
Hence comparing it with (A)

Applying the rule on (B)

Hence our answer is
