Answer:
x = 3
y= 1
Step-by-step explanation:
for x:
sin (60°) = x/2
x = (sin 60) × 2
x = √3
for y:
cos (60°) = y/2
y= 2 × (cos 60)
y= 1
Answer:
w=4
Step-by-step explanation:
18+3w=30
3w=30-18
3w=12
w=4
There is no exercise. I cannot answer it without an exercise.
Answer:
400
Step-by-step explanation:
angles that are coterminal with the angle 400? => 4000 and 7600 are two positive coterminal angles.
Answer:
1. x = (199/130)e^(-2t) - (33/65)e^(-4t) - (18/65)cos3t - (1/65)sin3t
2. x = (191/128) - (63/128)e^(-4t) + (t³/12) - (t²/16) + (t/32)
