Question

Find the length of side AB .Give your answer to 1 decimal place

Answer 1

Given: The figure.

To find: The length of side AB to 1 decimal place.

Solution:

The triangle shown in the figure is a right-angled triangle. The side AC is the perpendicular, the side BC is the hypotenuse and the side AB is the base.

The cosine of an angle is given by dividing the hypotenuse of the triangle by its base. Thus, it can be represented in the form of an equation as follows.

$tan 62 = \frac{12 cm}{AB}$

$1.88 = \frac{12 cm}{AB}$

$AB = 6.4 cm$

Therefore, the length of side AB to 1 decimal place is 6.4 cm.
