- Batdogs Justice
- Hi, I'm Batdog. I'm trying to enforce justice by catching my next criminal. Can you help me find him using trig?
- Bad CriminalLast seen at the Bank
- A2 = B2 + C2 - 2BCCosAX2 = 202+42 - 2(20)(4)(cos(67))X = 18.8 ft
- To get to the bank, we first have to jump this building. How tall is the building if the ladder is 20 feet tall, is 4 feet from the base of the building, and the angle between the ground and the ladder is 67°.
- X
- 4 ft
- 67°
- 20 ft
- Area = 1/2 BCSinAArea = 1/2 (12)(14)(sin(55))Area= 68.8 in2
- 55o
- 12in
- 14in
- Justice Bank
- Batdog has arrived at the Bank, to make sure he can get in the door he needs to know the area of the doggy door. We know that 2 sides of the triangle are 12in and 14in and the angle between those sides is 55o
- S = rθS = 6(π)S = 18.8 in
- Once batdog gets in the bank he sees a hole in the safe room door, help him find the arc length of the hole so he can get through and stop the criminal. The radius of the circle is 6 in. with a angle of π radians
- 6 in
- π
- Congrats!!! You helped Batdog enforce justice by catching this criminal. Someday when you wanna be the next Dark Knight, you'll be ready because you know trig!
