Answer:

56.714°

Step-by-step explanation:

Since we do not have a full angle of this proposed triangle, we must do this by splitting it into two right triangles instead of using the law of sines.

250m*sin(40°) = 250m*0.64278760968 = 160.696902422m

452.4m-160.696902422m=291.703097578m

Use pythagorean theorem:

\sqrt{250^2 - 160.696902422^2}

62500-25823.494448025787=36676.505552

\sqrt{36676.505551974216} = 191.511110779m

arctan(291.703097578m/191.511110779m)≈56.714°
