They want us to apply the sum angle formula to
5π/6 is 150°; I find it easier to think in degrees.
When the tangent of x is 3/4 that's a right triangle with opposite 3, adjacent 4 so hypotenuse 5. So a sine of 3/5 and a cosine of 4/5, both positive because we're told x is in the first quadrant.
The sine sum angle formula is
We know sin 150° = sin 30° = 1/2 and cos 150° = - cos 30° = -√3/2

Answer:
The fraction of frame did Monica paint blue is
Step-by-step explanation:
Given as :
The area of square frame = A = 24 square inches
Monica paint of one side of the frame blue
Let the measure of one side of frame = x
So, <u>From Area of square</u>
Area = side × side
Or, A = x × x
Or, x ² = 24
∴ x = = 2
So, Measure of each side = x = 2
Now, As Monica paint of one side of the frame blue
So, The painted part = × 2
∴ The painted part = ×
I,e The fraction of painted blue =
Hence, The fraction of frame did Monica paint blue is Answer
