- Everyday, the citizens of Trignomia are saved by the brave firefighters who put their lives at risk. In the following scenes, see how trigonometry helps them do their job.
- The first call of the day is Tyler, who has to rescue a cat from the tree. Using trigonometry, he must figure out the angle of elevation if he is using a 12 foot ladder and is 10 feet away. Solve using trig ratiosEquation: tanx = opposite/adjacent
- 10 ft
- x°
- 12 ft
- Meanwhile, Benny is 20 feet away from a house fire and 7 feet away from a fire hydrant. If the angle of elevation is 40°, how far away is the fire and hydrant. Solve using Law of Cosines.Formula: a2 = b2 + c2 - 2bc * cosA
- 40°
- 20 feet
- 7 feet
- x
- Lacey is in charge of saving a horse from a burning building. Using trigonometry, she needs to figure out which hose to use knowing that the height is 8 ft and angle of elevation is 40°. Figure out the distance using a trig ratio.Equation: sin40°= opposite/hypotenuse
- 40°
- x ft
- 8 Ft
- bob received a call saying a apartment building was on fire. when he arrived he saw that the fire was on the second floor, which is 17 ft from the ground.
- THE ENDTHE CITIZENS OF TRIGNOMIA HAVE ALL BEEN HELPED! THE POWER OF MATH IS SO STRONG!
