1. bob tried to answer the following question by finding the missing angle and rounding the answer to the nearest degree.
(see photo)
here is his solution
cosx =16/20
x=cos-1 (16/20) = 36.8698976 = 37degree
bob made a mistake in his work. explain the mistake and write the correct solution.
2) the following picture is a square pyramid where ae=6/2 cm and angle eab =45degrees.
find the surface area of the pyramid. (make sure you include formulas and numbers in the formulas as part of your solution. also include units in your final answer.)
