Answer:

indicated angle = 55.2°

Step-by-step explanation:

Hey there!

Here hypotenuse of 28 and opposite of 23 is given.

Using the sin rule:

[tex]\boxed{sin(a) = \frac{opposite }{hypotenuse} }[/tex]

[tex]sin(a) = \frac{23}{28}[/tex]

[tex]a = sin^{-1}(\frac{23}{28} )[/tex]

[tex]a = 55.2[/tex]
