Hi. -9/10 + 1/6 = (-54+10)/60 = -44/60 = -11/15.
We have
tan 12.5 = 60 / adj rearrange as
adj = 60 / tan 12.5 = about 270.64 m
It said my answer has to be 20 characters long but all you have to do is subtract so the answer would be 568
103 ft^2
take 3 and 5 and multiply it by 30
3*30=90
5.5*30=165
then divide them both by 12 to convert inches to feet
90÷12=7.5
165÷12=13.75
then multiply both dividends together
7.5*13.75=103.125
then round to the nearest whole number
103
