Here Radian measure of an angle=27π/4
we have to find the value of six trigonometric functions.
First i have converted radian measure of an angle into degrees.
27π/4=(27×180)÷4=1215°=3 Quadrants +135°=135°
which lies in second Quadrant.
As in second quadrant only sine, cosec ,function are positive.All other trigonometric function i.e cos,sec,tan,cot function will be of negative value.
It would be most likely rounded to the ten thousaths
For 2 pounds it would be 98 for 5 pounds 39.2 or 40
I think the value of x will be 6.
2x+2x+2x=12
6x=12
x=6
2(6) - 13
12 - 13
