AC=5sin65°

upper A upper C equals 5 sine 65 degrees

AC=5sin65°

upper A upper C equals Start Fraction 5 over sine 65 degrees End Fraction

AC=5sin25°

upper A upper C equals 5 sine 25 degrees

AC=5sin25°

upper A upper C equals Start Fraction 5 over sine 25 degrees End Fraction

BC is the hypotenuse (∠A = 90°), and AC is opposite ∠B (25°). So sin(25°) = AC/BC = AC/5, hence AC = 5·sin25°.
