Answer:
x = 
Step-by-step explanation:
Using the rule of exponents
= 
Note that 8 = 2³ and 2 =
, then
=
, that is
= 
Since the bases on both sides are equal, equate the exponents
3x = 1 ( divide both sides by 3 )
x = 
Answer:
12
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj / hyp
cos 60 = 6/hyp
hyp = 6 / cos 60
hyp = 6 / (1/2)
htp = 12
