2d +9= 19
The solution is d =

Hello there, first we can place our equation, which you have stated
, this algebra, in algebra we want to find the exact value of the variable, or have the variable on one side of the equation.
First we can subtract
with both sides of the equation giving us the result of
, this can also be represented as
, now just divide both sides of the equation by
, our answer is
.

Your answer should be the 3rd choice. There is no solution.
Answer:
I believe its 63°......,.,..,.,.,.,
The answer is 145 divided by tan 65 degrees.
Since the equation for tangent is opposite/adjacent, you can just plug the numbers in.
tan(65)=145/x (x being the height that you are trying to find)
tan(65) * x = 145
Then divide tan(65) to isolate the x and you get:
145/tan(65)
Hope this helps!
Y=-11. 2×-4 is -8, and -8-3 is -11.
