Let's say it's the angle γ = 30° between the sides 5 and 6. Then: Recall the law of cosines formula c² = a² + b² - 2ab × cos (γ) Plug in the values a = 5, b = 6, γ = 30°. We obtain c² = 25 + 36 - 2 × 5 × 6 × cos (30) ≈ 9. Therefore, c ≈ 3. how to setup voicemail on tracfone

Websin 4 x + cos 4 x = ( e i x − e − i x 2 i) 4 + ( e i x + e − i x 2) 4 Notice that i 4 = + 1, so we get sin 4 x + cos 4 x = 1 16 ( 2 e 4 i x + 2 e − 4 i x + 12) where we use the relation ( a + b) 4 = a 4 + 4 a 3 b + 6 a 2 b 2 + 4 a b 3 + b 4. The terms of the form a 3 b and a b 3 all cancel by addition. This leaves us with a final result: WebExplanation for the correct option: Solve the expression cos 4 θ – sin 4 θ = ( cos 2 θ) 2 – ( sin 2 θ) 2 = ( cos 2 θ + sin 2 θ) ( cos 2 θ – sin 2 θ) ; ∵ a 2 - b 2 = ( a + b) ( a - b) = 1 × ( cos 2 θ – sin 2 θ) ; ∵ s i n 2 θ + c o s 2 θ = 1 = cos 2 θ – ( 1 – cos 2 θ) = 2 c o s 2 θ – 1 Hence, Option ‘B’ is Correct.
