Step-by-step explanation:
the formula is too long so the link is below:
https://www.geteasysoloution.com/1/3x+12=x-4
Tan w=20/83
inverse tan 20/83=13.55 degrees
<span>X^2- 4x- 6y- 14=0
6y = x^2 - 4x - 14
Divide through by 6:-
y = (1/6)x^2 - (2/3)x - 7/3</span>
Complelment adds to 90
let's say the complement is B
A+B=90
4x+2+B=90
minus (4x+2) from both sides
B=88-4x
