Use the rational root theorem:

=16,

=1
The dividers of

: 1,2,4,8,16
The dividers of

: 1
Therefore, check the following rational numbers: +-


is a root of the expression, so factor out x-4
Compute

to get the rest of the equation.

Cancel the common factor:

is the final answer
Answer:
Which equation do I refer to?
Step-by-step explanation:
Answer:
C) Z
Step-by-step explanation:
In the right triangle, X and Y are side lengths, while Z is the hypotenuse, so C is the correct answer.
SOH CAH TOA
Sine is opposite over hypotenuse so you're answer is C.

Total Unit of Triangle = 2+4+9 = 15
Value of one unit = 180/15 = 12
So, Angles = 2(12) : 4(12) : 9(12) = 24 : 48 : 108
In short, Your Angles would be: 24, 48 & 108
Hope this helps!
