What grade level is this ??????????
Use the Pythagoras theorem :-
length = sqrt (72^2 + 60^2)
= 94 meters to nearest meter
1. Sin 240 degree = -sin ( 240 -180 degree) = -sin (60 degree)
2. Tan 130 degree = -tan ( 180 - 130 degree) = -tan 50 degree
3. sec 305 degree = sec ( 360 - 305 degree) = sec (55 degree)
4. cos 95 degree = -<span>cos (180 - 95 degree ) = -cos 85 degree</span>
5. csc 185 degree = -sin 5 degree
both 95s because to average you add them all and divine by the number of things your adding by
96+86+78+95+95=450/5=90
