Answer:
9.4
Explanation:
The law of cosines tells you ...
c^2 = a^2 + b^2 -2ab·cos(C)
where a and b are the side lengths on either side of angle C, and c is the side opposite that angle. For the values given here, we have ...
c^2 = 8^2 +15^2 -2·8·15·cos(33°) ≈ 87.7191
x = c ≈ √87.7191 ≈ 9.4 . . . . . the side opposite the given angle
The value of x is about 9.4.
