Look i sure someone will answer it soon good luck buddy I have faith in you
Step-by-step explanation:
tanX is 12/5.
Given:
In a right triangle,
The length of the side <em>XY</em> = 13.
The length of the side <em>YZ</em> = 12.
The length of the side <em>XZ</em>= 5.
The objective is to find tan <em>X</em>.
In a right angled triangle the largest side is always hypotenuse.
Sinec tan <em>X</em> is required to solve, then, the side <em>YZ </em>is opposite side and the side <em>XZ</em> is adjacent side.
By the trigonometric ratios, the value of tan <em>X</em> can be calculated as,

Hence, the value of tanX is 12/5.
The lowest elevation in New Mexico is 2,842 feet and the lowest in California is -282 feet ( negative because its below sea level.)
Then just:
2,842 - (-282) = 3,124 ft.
K-k+k-3
Then -k+k boom!! Canceled out!! OK
Only +k-3 left..
Transpose 3 to the other side it will be k=3
Done!!
Cross multiplication, 3(9+x) = 63
27+3x = 63
3x = 63-27 = 36
x=36/3=12
