WebMar 27, 2024 · Explanation: You can use the sin angle sum formula: sin(A +B) = sinAcosB + sinBcosA. Since 255∘ is the sum of 225∘ and 30∘, we can write: = sin(255∘) = sin(225∘ + 30∘) = sin(225∘)cos(30∘) + sin(30∘)cos(225∘) Here's a unit circle to remind us of some sin and cos values: = sin(225∘)cos(30∘) + sin(30∘)cos(225∘)
