diving board
Storyboard Text
- Jacy's day at the pool
- WOW! Cool diving board. I'm curious about how tall it is... just to be safe. I know it is 6 feet from the point on the ground and it has an angle of elevation of 25 degrees.
- I will use the tangent ratio.tan(25)=height/66tan(25)=heightthe height is 2.8 feet!
- 6 feet
- 25 degrees
- That isn't too tall. YAY! Now I will jump!
- WOAH! Cool new sign. I wonder how long the missing side is if the measurements are:a=5, b=4 and A=30degrees B=130degrees and C=20 degrees
- DANGERno lifeguard on duty
- After doing the math, I found out that the missing side is 3.4. All I did is use the Law of Sines. Sin(30)/5 = sin(20)/c. I did some algebra to find the missing side. What a cool sign!!!!
