: ok i took a test on trig n i dun get how i missed some of the questions... can u explain how to do them?
: 1). Given sin x=.8860 Find tan x correct to four decimal places. i got 1.664
You wrote your answer to 4 DIGITS,. You need one more to get to four DECIMAL PLACES. I dont know if the calculations are correct because i never took trig.
: 2). in right triangle, BCD, BD=12, the measure of angle C=90 and the measure of angle DBC=47. Find BC to the nearest tenth. i got 8.8
