The measure of the angle [tex]m<BAC=tan^{-1}\frac{12}{5}[/tex]

In order to determine the measure of m<BAC from the given diagram, we will have to find the measure of angle m<BAC

From the triangle

Hypotenuse = 13

Opposite = 12

adjacent = 5

Based on SOH CAH TOA

[tex]tan \theta = \frac{opposite}{adjacent}\\tan \theta =\frac{BC}{AC}\\tan \theta = \frac{12}{5}\\m<BAC=tan^{-1}\frac{12}{5}[/tex]

Hence the measure of the angle [tex]m<BAC=tan^{-1}\frac{12}{5}[/tex]
