1/3 because if so, it would be D) Reasoning: Applying sine rule to the triangle ABC, sin [90° - (12.5° + θ)] / 650 = sin(12.5°) / 150 => cos (12.5° + θ) / sin(12.5°) = 650/150 => cot(12.5°) cosθ - sinθ = 13/3 => 4.5107 cosθ - sinθ = 4.3333 =>
do the choices happen to be: A. 5°54' B. 7°10' C. 6°12' D. 7°50 ?
Let A = top of the tower, B = base of the tower and C = point of observation => ∠ ACB = 12.5° Let θ = angle of inclination of the hill to the horizontal plane. => ∠ CAB = 90° - (12.5° + θ) Applying sine rule to the triangle ABC, sin [90° -
hi!!! it's kesha and i would like to help! First, Simplify 8(3m + 5) = 2m + -4 Reorder the terms: 8(5 + 3m) = 2m + -4 (5 * 8 + 3m * 8) = 2m + -4 (40 + 24m) = 2m + -4 Reorder the terms: 40 + 24m = -4 + 2m Solving 40 + 24m = -4 + 2m Solving for variable 'm'.
