Answer:

B. 75°

Step-by-step explanation:

To get the value of the angle;

180°-105°= 75°.................sum of angles on a straight line

What is the area of a section of pavement that is 20 ft wide and 70 yd long?

myrzilka [38]

Answer:

A = 4200 ft^2

We need to have the same units

convert yd to ft

1 yd = 3ft

Multiply each by 70

70 yds = 210 ft

A = 210 *20

A = 4200 ft^2
