When you divide a fraction by another fraction, it is the same thing as multiplying that fraction by its reciprocal.
The reciprocal is the 'flipped' version of a fraction where the numerator becomes the denominator and the denominator becomes the numerator.
for example, the reciprocal of 9/10 is 10/9
Knowing this information 4/5÷9/10 is the same as 4/5×10/9
Now we can solve...

Answer= 8/9
The answer is A just trust me
It depends upon favorable outcomes so we need favourable outcome first
Answer: The display becomes skewed left.
Step-by-step explanation:
Hello!
The easiest way to solve for the value of both angles is to reduce the given angle to an acute angle.
Given that both of the angles are located in the second quadrant (90° < x < 180°), we use these reduction formulas: sin(180° - x) = sin x, and cos(180° - x) = -cos x, when x is equal to 150°.
Notice that cos is negative while sin is positive. In the first quadrant, sine is always positive and while in the fourth quadrant, cosine is always positive while sine is not.
sin(180° - 150) = sin 30 = 1/2 (using the unit circle)
cos(180° - 150) = -cos 30 = -√3/2 (using the unit circle)
<u>Final answers</u>:
- sin 150° = 1/2
- cos 150° =
