This storyboard does not have a description.
Jimmy is looking at a billboard on top of his building that is 50 meters away . he is looking at the billboard at an angle of 70. He is trying to figure out how high the billboard from the ground, so he uses trig to help him. Jimmy figures out that 50sin(70)=47. therefore the billboard is 47m high from the ground.
Jimmy's house is on the last floor of the building. His distance to his suite is 41m and the distance from the ground to his suite is 38m. he is now trying to find the angle of elevation from where he is standing. He uses trig. he finds out that the angle is sin (38/41)=68. The angle of elevation is 68
Jimmy remembers that he forgot his keys at the office but he can still go up the emergency stairs on the side of the building which leads to his balcony.
