If they do not have solutions (intersections).
If they do not have intersections then they must be parallel. Imagine it on the graph
<u>solution</u>
W=f×d×cos theta
=25N×16m×cos 45°
=400Nm×cos 45°
=282.84J
W=f×d×cos theta
=25N×7m×cos 10°
=175Nm×cos10°
=172.34J
Total workdone=282.84J+172.34J=455.18J
Answer:
Complementary angle is 90 degree and supplementary angle is 180 degree
162 / 2 = 81
the answer is D
