Answer:
63.57817848
Step-by-step explanation:
all will be in degrees:
cos 40 sinx - sin 40 cos x = sin(x - 40) by the formula sin(A − B) = sinA cosB − cosA sinB
sin(x - 40) = 2/5
x - 40 = arcsin(2/5)
x - 40 = 23.57817848
x = 63.57817848 degrees
Step-by-step explanation:
m and n are both located on the number line and are on the left of 0.
Therefore m and n are both negative reals.
m¹³ * n⁵
= (-)¹³ * (-)⁵
= (-) * (-)
= (+)
The answer is positive.
Answer: Root 3 / 3
Step-by-step explanation: Use unit circle trigonometry.
first you take 3.14*10^2
10*10=100, 3.14*100=314in^2
