There's the guard! I should really take this moment seriously. Now how do I shoot him??
Blue, a hero capable of dispatching enemies efficiently, gets a mission to initiate an attack on the enemy's base in their least guarded area.
Time to use the ability of my mask!
Blue can now see how far he is from his opponent and uses this opportunity to strike. But he doesn't know the angle he needs to shoot from.
His mask gives him info. According to it, he is 28 meters away from the stand. The stand itself has a height of 25 meters. His mask also gives him additional info about the distance his sight is from the guard, which is 38 meters.
He now needs to find the angle, or θ. To find this angle, he uses the equation cosθ = 28/38. He remembers cos is adjacent over hypotenuse. To find the angle, he proceeds to use the equation θ = cos^-1 (28/38). He finds that the angle is 43°.
θ = 43°
Out of my way!!
θ = 43°
Headshot. Group C, initiate attack in Site C!!
And just like that, the guard is down, paving the way for Blue and his comrades to attack.
