What is the trigonometric ratio for sin s triangle q r s with right angle r. q s equals 68. r s equals 60.

Trigonometric ratio for sin S = 0.471

Explanation:

 From figure we have sin S = QR/QS

 QS = 68

 By Pythagoras theorem we have,

    QS² = QR² + RS²

    68² = QR² + 60²

    QR² = 68² - 60²

    QR = 32

  sin S = QR/QS = 32/68 = 0.471

Trigonometric ratio for sin S = 0.471

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
