Given: zabc is a right angle and zdef is a right angle. prove: all right angles are congruent by showing that zabc - zdef. what are the missing reasons in the steps of the proof? labc, zdef are right angles młabc = 90°, m_def = 90° m abc = m_def zabc = zdef given b:

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.
