The scale drawing represents a plot of ground for growing vegetables. Plot A:

Right side of square: 1 3/8

Bottom side of square: 2 1/4

Scale drawing: 1/8 inch corresponds to 5 feet.

What is the actual area of ground, in square feet, for growing vegetables?

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
