Answer: $87.7^{\circ}$

Step-by-step explanation:

Height of the building AB= 443 meters

Distance between the building and the agent at the ground BC= 18 meters

Let x be the angle the agent should shoot his laser gun

Since ΔABC is a right triangle, then

$\tan\ x=\frac{AB}{BC}$

$\Rightarrow\tan\ x=\frac{443}{18}\\\Rightarrow\tan\ x=24.6111\\\Rightarrow\ x=\tan^{-1}(24.61)\\\Rightarrow\ x=87.67^{\circ}\approx87.7^{\circ}$
