2/3 x 3/4 =6/12=1/2
(Multiply numerators, multiply denominators, simplify)
2 units i believe but not entirely sure
8 ^ (-2) = 1 / 64
<span>4 ^ (-3) = 1 / 64</span>
The Answer is b. Hope that helps
Step-by-step explanation:
using trig, tangent is equal to opposite over adjacent.
in this case, the angle is 45, opposite is 7, and adjacent is a.
thus tan 45° = 7/a
solve for a to get a = 7/tan 45° = 4.32
