The equation   can be used to find the measure of ∠BAC ⇒ 2nd answer
 can be used to find the measure of ∠BAC ⇒ 2nd answer
Step-by-step explanation:
Let us revise the trigonometry ratios in the right triangle ABC, where B is the right angle, AC is the hypotenuse, AB and BC are the legs of the triangle
The trigonometry ratios of the ∠BAC, the opposite side to this angle is BC and the adjacent side to it is AB are
In Δ ABC
∵ ∠ BCA is a right angle
∴ The hypotenuse is AB
∵ The adjacent side to ∠CAB is AC
∵ The opposite side to ∠CAB is BC
∵ AB = 13 units ⇒ hypotenuse
∵ CB = 12 units ⇒ opposite
∵ AC = 5 units ⇒ adjacent
- Let us find the trigonometry ratios of angle BAC
∵ m∠CAB is x
∵ 
∴ 
∴

Answer:
The polynomial is  2 x² - 2x + 7
Step-by-step explanation:
Given polynomial 
                    (8 x² + 9 ) - (6x² +2x +2)
            =   8 x² +9 - 6x² - 2x -2
           =    8x² - 6x² - 2x + 9-2
          =    2 x² - 2x + 7
The polynomial is   2 x² - 2x + 7
