Question

Find the sine of Write your answer in simplified, rationalized form. Do not round.

Please help!!!!!

Answer 1

Sin (E) = √74/(2√23)

Explanation:

Reference Angle = E

Hypotenuse = 2√23

Adjacent = 3√2

Opposite = DC = √(2√23)² - (3√2)²) = √(4*23 - 9*2) = √(92 - 18) = √74 (pythagorean theorem)

Recall SOHCAHTOA.

Thus,

Sin (E) = opp/hyp

Sin (E) = √74/(2√23)
