Find the m∠BAC, if m∠DEC = 45° and m∠EDC = 65°.
50°
60°
<u><em>70° </em></u>
80°

Answer: C - 70° Proof: Since ED || CB and CD || AB, then ∠ACB = ∠CED (corresponding angles along parallel lines; BC || DE) Also, ∠DCE = ∠BAC (corresponding angles along parallel lines; AB || CD) Thus, ∠BAC = ∠DCE = 180 - (45 + 65) = 70° (ie C)

Write each vector as a linear combination of the vectors in s. s = {(2, 0, 7), (2, 4, 5), (2, −12, 13)} (a) u = (−1, 7, −7)
Paladinen [302]
The vectors in s are linearly dependent, but you can make u from .. (2, 4, 5)/16 -9*(2, -12, 13)/16 = (-1, 7, -7)
a = 4, h = 3

Input : a = 5, h = 10
Output : Surface Area: 429.904
