Answer:

AC=8.24

Explanation:

In the figure given in the question we have to find AC.

Given:

BC=3

∠B=70° and

ΔACB is right-angled at C.

The best way to find the answer is by using trigonometry.

We know that tan of an angle is
$(opposite\ side)/(adjacent\ side)$ .

tan∠B =

AC = BCtan70°=3×tan70°

AC = 8.24 (rounding off to nearest hundredth).
