WebTo find the value of sin 68 degrees using the unit circle: Rotate ‘r’ anticlockwise to form a 68° angle with the positive x-axis. The sin of 68 degrees equals the y-coordinate (0.9272) of the point of intersection (0.3746, 0.9272) of unit circle and r. Hence the value of sin 68° = y = 0.9272 (approx) ☛ Also Check: sin 45 degrees sin 50 degrees WebNov 14, 2024 · Find the value of x in the given figure. Solution: Step 1: We know that the sum of the internal angles of a quadrilateral equals 360 degrees, so we can say that (3x + 3)0 + 120 ∘ + 600 + 120 ∘ = 360 ∘ …
