In the diagram, QTR is a straight line and o. find the sin of
- A.
(frac{8}{15}) - B.
(frac{2}{3}) - C.
(frac{3}{4}) - D.
(frac{15}{16})
Correct Answer: Option C
Explanation
(frac{10}{sin 30^o} = frac{15}{sin x} = frac{10}{0.5} = frac{15}{sin x})
(frac{15}{20} = sin x)
sin x = (frac{15}{20} = frac{3}{4})
N.B x =
