Mathematics

BA = 6.0

BC = 13.4

Step-by-step explanation:

Given

The attached triangle

Solving (a) BA

Considering the tangent of angle C, we have:

$tan\ C = \frac{BA}{AC}\\$

This gives:

$tan\ 25 = \frac{BA}{12}$

Make BA the subject

$BA = 12 * tan\ 25$

BA = 12 * 0.4663

BA = 6.0 --- approximated

Solving (a) BC

Using Pythagoras theorem

BC^2 = BA^2 + AC^2

BC^2 = 6.0^2 + 12^2

BC^2 = 180

Square root of both sides

$BC = \sqrt{180$

BC = 13.4
