The angle of elevation of shadow from building is 50 degrees
tan 50=height of building/length of shadow=h/75
h=75tan50=75(1.192)=89.38 feet
the height of the building is 89.38 feet
Since the exchange rate of euro to USD right now is 1:1.11, therefore he spent 150x1.11=166.5 USD. Therefore, he has 250-166.5=83.5 USD left(assuming the exchange rate is the same, 1.17).
