Question

Use graph to answer question

Answer 1

Given:

A figure of a right angle triangle.

To find:

The length of BC.

Solution:

In a right angle triangle,

`\tan \theta =(Perpendicular)/(Base)`

In the given triangle,

`\tan A =(BC)/(AC)`

`\tan 23^\circ =(BC)/(6)`

`0.42447* 6 =BC`

`2.54682 =BC`

Approximate the value to the nearest hundredth.

`BC\approx 2.55`

Therefore, the measure of side BC is 2.55 units.
