Step-by-step explanation:
By applying sine rule in the given triangle,
cos(25°) =
cos(25°) =
b = 400[cos(25°)]
b = 362.52
b = 363 ft
By applying sine rule in the given triangle,
sin(25°) =
sin(25°) =
a = 400[sin(25°)]
a = 169.05
a = 169 ft
m∠A + m∠B + m∠C = 180°
25° + m∠B + 90° = 180°
m∠B = 180° - 115°
m∠B = 65°
