The 2 sides are 9.6 and 7.22
Explanation:
I recommend you draw a sketch.
using basic 'trig ratios' for the right triangle
where o represents opposite side , a, adjacent and h , hypotenuse.
#• sinx = o/h#
#• cosx = a/h # then cos37º =
# a/12 rArr a = 12cos37º ≈ 9.6 # [The 3rd side could be calculated using Pythagoras' Theorem.]
and
# sin37^@ = b/12 rArr b = 12sin37^@ ≈ 7.22 #
