#### Storyboard Text

• Hi Jim! I'm trying to figure the angle in which I'm looking at the top of the church at from the ground. Do you mind helping me figure it out?
• No, of course not, so, what do you need?
• Let's be on our way then!﻿
• After you
• From where my head is, the distance between my head and the very middle of the church is approximately 5 meters.
• So, how far exactly are you going to be standing away from the church?﻿
• How about the distance between from where your head is and the top of the church? Also the height of the church from top of it's entrance and the peak of the church?﻿
• My heads 10 meters away from the top of the church, and the height from the doors to the top of the cross is around 8 meters.﻿
• 10 meters﻿
• 5 meters
• 30﻿
• 90° ﻿
• 8 meters
• The formula to finding the unknown angle here is  cos-1 (also known as the inverse) multiplied by the adjacent divided by the hypotenuse.
•   cos-1  (5/10) will give you the angle which is 60 degrees.
• Wow! that was easier than I thought! Thank you so much!!﻿
• Anytime Jim!
