Answer:
Sin A = 0.38462
Explanation:
From the trigonometric function,
Sin A =
................... 1
So that, applying the Pythagoras theorem to determine the value of hypotenuse,
=
+

=
+

= 576 + 100
= 676
Hyp =

= 26
The hypotenuse of the triangle is 26.
Thus, from equation 1;
Sin A =

Sin A = 0.38462
