Answer:
[tex]A= 53[/tex]
Step-by-step explanation:
Given
[tex]BC = 9,6[/tex]
[tex]AC = 7.2[/tex]
Required: Angle A
This is calculated using:
[tex]tan\ A = \frac{Opposite}{Hypotenuse}[/tex]
From the attachment;
[tex]Opposite = 9.6[/tex]
[tex]Adjacent = 7.2[/tex]
So:
[tex]tan A =\frac{9.6}{7.2}[/tex]
[tex]tan A =1.333[/tex]
Take arctan of both sides
[tex]A= tan^{-1}(1.333[/tex]
[tex]A= 53[/tex]----- approximated
