What are the angle measures of triangle abc?
(1) - ma = 30°, m b = 60°, mc = 90°
(2) - ma = 90°, m2b = 60°, m2c = 30°
(3) - ma = 60°, m2b = 90°, m_c = 30°
(4) - ma = 90°, m b = 30°, m2 = 60°

When a formula is solved for a particular variable, several different equivalent forms may be possible. if we solved a=1/2bh for h, one possible correct answer is h=2a/b . which one of the following is not equivalent to this? a. h= 2(a/b) b. h= 2a(1/b) c. h= a/1/2b d. h= 1/2a/b

Asequence {an} is defined recursively, with a1 = 1, a2 = 2 and, for n > 2, an = an-1 an-2 . find the term a241
