For the tringle shown what are the :
my answer :
a )c = a2 - b2
81 - 49 = root 32
b ) tan Q = 2/7 = 0.28
C ) the angle sin = 9/7 = 1.28
(a) Right.
(b) No, it's the opposite side upon the adjacent side. So, it becomes $\displaystyle \frac{7}{\sqrt{32}}$ (I'm assuming that the angle Q is only the upper one.
(c) For this one, use what you just found.
$\displaystyle \tan Q = \frac{7}{\sqrt{32}}$
$\displaystyle Q = arctan \frac{7}{\sqrt{32}}$
