4. The angle of elevation from the roof of a 10 m high building to the top
of another building is 41°. The two buildings are 18 m apart at the base.
a) Which trigonometric ratio would you use to solve for the height of
the taller building? Why?

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
