Answer:
14
Step-by-step:
A triangle has 3 sides, 2 of which we know and need to use in this question, i.e, 8√7 and X (which we need to solve for).
X is opposite to that 45° angle, which makes it the "opposite" and the 8√7 is the "hypotenuse"
When solving questions like this one, remember the acronym SOH CAH TOA which means: sinσ =
cosσ =
tanσ =
NB: σ= the known angle
For
all possible rational zeroes are all the possible factors of the constant term -2 express over coefficient of the term with the highest degree of the polynomial which is 3
These are

Answer: x = -0.6
-2x + 3.25 = 0.5x + 4.75
- 3.25 - 3.25
-----------------------------------
-2x = 0.5x + 1.50
-0.5x -0.5x
-----------------------------------
-2.5x = 1.50
(Divide both sides by -2.5 to get x by itself)
x = -0.6
