The sine of the angle =length of the opposite side.

The cosine of the angle =length of the adjacent side

Tangent of the angle of the opposite side.

In this case we are looking for the adjacent side to given angle so use Cosine

Cos 70=x/46

X=cos70×46

Cos 70=1.5341

X=46Cos 70

X=46×0.3420

X=15.732

Answer 2

Explanation:

Cos 70 = x/46

x= 46cos70

=29.13

= 29
