Question

From a boat on the lake, the angle of elevation to the top of a cliff is 26°1'. If the base of the cliff is 205 feet from the boat, how high is the cliff (to the nearest foot)?

Answer 1

first off hmm 26°1' is just 26 degrees and 1 minute

there are 60 minutes in 1 degree, so 1minute is just 1/60 degrees
so 26°1' is 26° + (1/60)°  or 26.1667 rounded up, since 1/60 is a recurring unit

alrite... so hmm, check the picture below

make sure your calculator is in Degree mode.
