What is the value of tan A?
Ronch [10]

For the given triangle, the tan of angle A equals \frac{3}{4} = 0.75.

Step-by-step explanation:

Step 1:

In the given triangle for angle A, the opposite side has a length of 6 cm, the adjacent side has a length of 8 cm while the hypotenuse of the triangle measures 10 cm. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.

tan A = \frac{oppositeside}{adjacent side}.

Step 2:

The opposite side's length = 6 cm.

The adjacent side's length = 8 cm.

tan A = \frac{oppositeside}{adjacent side} = \frac{6}{8} = \frac{3}{4} = 0.75.
