cos(35)sin(55)+sin(35)cos(55)
If we rewrite this switching the first and second terms we get:
sin(35)cos(55)+cos(35)sin(55)
which is a more common form of the sin sum and difference formulas.
Thus this is equal to sin(90) and sin(90)=1

ENE plus 90 degrees (clockwise) is SSE.
An angle of 366 degrees is a full turn plus 6 degrees
1) x=21 2) x=14.45
The inside angles of a triangle always add up to 180 degrees.If you mean angle a plus angle b equal 85 degrees, then angle c must be 95 degrees.If you mean angle a is 85 degrees and angle b is also 85 degrees, then angle c must be 10 degrees50 degrees :)
The direction NNW plus 90 degrees is ENE. ---------------------- NW is a bearing of 315 and NNW is a bearing of 337.5. Add 90 to this, and subtract 360 because we have "gone round": 337.5 + 90 = 427.5; 427.5 - 360 = 67.5. This is past NE, so the answer is ENE.
