So i was trying to solve a problem as listed as below.
From a boat on the lake, the angle of elevation to the top of a cliff is 29°38ʹ. If the base of the cliff is
655 feet from the boat, how high is the cliff (to the nearest foot)?
I am unsure how to approach this problem because i dont get what 29°38ʹ is!
is it trying to tell me that it is 29 degree and 38 ft??(Worried)
No, it's 29 degrees and 38 minutes. A minute is 1/60 of a degree.
so,, would it mean 29 and 38/60 degree?? how do i solve that? please help me! i am very confused
Draw a diagram. Use trig.

oh thanks! Now i can solve it!
I could not do that and that is why i posted here
Fun fact: Minute means "minute." "Second" means second minute part of an hour (or degree), so "minute" is, in fact, first minute part of an hour.Quote:

tan A=P/B
here p=perpendicular
b=base
so tan(29 degree and 38 min)=P/655
In this question we can easily find out the value of tan29 but got 38 we have to check its value from table
