2/3 x = 4h

x = 3/2 . 4h

x = 6h

The storybooks they have in total would be : 6h + 4h = 10 h

hope this helps

I need help finding the reference angles for these angles.

Salsk061 [2.6K]

Convert the angles to degrees. Remember there are 2pi radians in a circle, and a circle has 360 degrees, so conversion factor is 180degrees/pi. Then you can easily approximate the reference angle. Remember you make the reference angle from the positive x-axis and the reference angle will be the angle between the terminal side and the nearest x-axis (either positive side or negative side of the x-axis).
1) $1.4 * \frac{180degrees}{pi} = 80.214 degrees$
2) $-1.4 \pi * \frac{180degrees}{ \pi } = -252 degrees$
