The diffrence of a number m and 30 is 10

Arandom high school question but a hard one

In the diagram below, tan θ = sqrt 3. what is the value of m?

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)
