find sin 16.sin48.sin 74.sin42 = ?
Answers
Answer:
Explanation:in74° = 0.96126sin 74 ° = 0.96126sin 74 degrees = 0.96126The sin of 74 ... To calculate sin 74 degrees insert the angle 74 in the field labelled °, but if ... cos (90°-74°) = cos 16°.
Concept:
Trigonometric angles are used to represent the Trigonometric functions in an angle of a right-angled triangle to ratios of two side lengths.
Given:
We have,
Sin 16 × sin48 × sin 74 × sin42
Find:
We are asked to find the value of Sin 16 × sin48 × sin 74 × sin42.
Solution:
We have,
Sin 16 × sin48 × sin 74 × sin42
So,
Using the Trigonometric angles,
i.e.
Sin 16° = 0.275637
Sin 42° = 0.669131
Sin 48° = 0.743145
Sin 74° = 0.961262
So
Now,
putting values,
we get,
Sin 16 × sin48 × sin 74 × sin42
i.e.
= 0.275637 × 0.669131 × 0.743145 × 0.961262
On solving,
We get,
= 0.12315
i.e.
Sin 16 × sin48 × sin 74 × sin42 = 0.12315
Hence, the value of Sin16 × sin48 × sin 74 × sin42 of is 0.12315.
