\tan(\Theta) = \dfrac{\text{opp}}{\text{adj}}

\tan(43) =  \dfrac{x}{12}

x = \tan(43) \times 12

x = 11.2

You have 2 legs and the angle, the angle is opposite to the leg, 
so we can write TAN of the angle

tan(43°)= (opposite leg)/(adjacent leg)
tan(43°)= x/12
x=12*tan(43°)≈ 11.2

Answer:

<h2>{x}^{2}  + 9x - 16</h2>

Step-by-step explanation:

4 {x}^{2}  + 8x - 7 - (3 {x}^{2}  - x + 9)

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression:

4 {x}^{2}  + 8x - 7 - 3 {x}^{2}  + x - 9

Collect like terms

4 {x}^{2}  - 3 {x}^{2}  + 8x + x - 7 - 9

{x}^{2}  + 9x - 7 - 9

Calculate

{x}^{2}  + 9x - 16

Hope this helps...

Good luck on your assignment...
