WebOct 21, 2024 · If in ΔABC, ∠C = 90°, then sin (A + B) = (a) 0 (b) 1/2 (c) (d) 1 Answer 20. If sin A – cos A = 0, then the value of sin 4 A + cos 4 A is (a) 2 (b) 1 (c) (d) Answer 21. Ratios of sides of a right triangle with respect to its acute angles are known as (a) trigonometric identities (b) trigonometry (c) trigonometric ratios of the angles WebTherefore you need the trig function that contains both the OPPOSITE and the HYPOTENUSE, which would be SINE, since sin = OPPOSITE / HYPOTENUSE. "Let's input the value into the equation." sin (deg) = opposite/hypotenuse sin (72) = 8.2/DG "Since we're solving for DG, the hypotenuse, we have to move it so that it is on the numerator.
