Question

Given 

a) state the other five trigonometric ratios as fractions.

b) determine the value of  to the nearest degree.

Answer 1

tanT = -9/4

cotT =-4/9

hypotenuse = sqr(9^2+4^2) =sqr(81+16) =sqr97

sinT = -9/sqr97 = about -900/985 = -180/197

cscT = -sqr97/9 = about -985/900 =-197/180

cosT =4/sqr97 = about 400/985 = 80/197

secT =sqr97/4 = about 985/400 = 197/80

T = 360-66.0375 = 293.9625 degrees= about 294 degrees rounded to nearest degree
