Answer:
choice 3)
JK = 3.51
WK = 9.15
∠J = 69°
Step-by-step explanation:
sin 21° = JK/9.8
0.3584 = JK/9.8
cos 21° = WK/9.8
0.9336 = WK/9.8
WK = 9.15
∠J = 90° - 21° = 69°
Answer: 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
As you can see from the graph I attached you, the possible solutions in the interval from 0 to 2π are approximately:
So, it's useful to solve the equation too, in order to verify the result:
Taking the inverse sine of both sides:
Using this result we can conclude the solutions in the interval from 0 to 2π are approximately:
