An object is moving at a speed of 6 miles per month. Express this speed in feet per hour.

If a and b are the measures of two first quadrant angles and sin a = 4/9 and sin b = 2/5 find sin(a+b).

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.
