We can then set up an equation with just the arguments: 50 - x + 3x + 10 = 90. 2x + 60 = 90. 2x = 30. x = 15. 3 comments.
WebCos 13 degrees is the value of cosine trigonometric function for an angle equal to 13 degrees. Understand methods to find the value of cos 13 degrees with examples and FAQs. ... Example 1: Find the value of 2 cos(13°)/3 sin(77°). Solution: Using trigonometric identities, we know, cos(13°) = sin(90° - 13°) = sin 77°. ⇒ cos(13°) = sin(77°)
WebSince the cosine function is a periodic function, we can represent cos 22° as, cos 22 degrees = cos (22° + n × 360°), n ∈ Z. ⇒ cos 22° = cos 382° = cos 742°, and so on. Note: Since, cosine is an even function, the value of cos (-22°) = cos (22°).
