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
Answer:
1. x >/= -1
2. x < 4
3. x </= -1
4. x >/= -2
5. x < -3
6. x </= 7
Step-by-step explanation:
You divide 2.5 to both the miles and hours to get 1 hour and the miles remain.
The answer is 54 miles
= 6 - {-4+[3-(-13) +14]-7}
= 6 - {-4+[3+13+14]-7}
= 6 - {-4+[30]-7}
=6- {19}
=-13
answer is minus thirteen
No, because 3/8=30/80 and 4/10=32/80.
