Question

Use the table for sine values, and find x to the nearest tenth.

x

Answer 1

Recall that the sin of the angle is the hypotenuse over the opposite side. So in this case:
\[sin\ 70^{\circ} = {x \over 10} \implies x = 10(sin\ 70^{\circ})\]

Answer 2

Should make it pretty easy to answer from the table..

Answer 3

10sin70=9.4

Answer 4

not right
