Answers If sin θ = -1/2 for 0 If sin θ = -1/2 for 0 o, the value of θ is A. 30o and 150o B. 150o and 210o C. 210o and 330o D. 150o and 330o Correct Answer: Option C Explanation sin θ = -1/2 = -0.5 θ = sin-1 (0.5) θ = 30o Since θ is negative θ = 180 + 30 = 210o θ = 360 – 30 = 330o ∴θ = 210o and 330o `, props: [‘comment’], data() { return {} }, methods: {} }) {{ reply.posted_by.display_name }}: {{ reply.created_at }} If sin θ = –1/2 for 0 o, the value of θ is A. 30o and 150o B.… Read More
