16.80 times .20= 3.36
answer: the proof is mentioned below.
since, given: lines bc = ef
prove: lines ac > ef
1. bc=ef 1. given
2. ac= ab+bc 2. because b is the point between the
line segment ac
3. ac > bc 3. because if a line segment is equal to
the sum of two line segments then it is
always greater then each of these
individual line segments
4. ac > ef 4. by equality property.
if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
