Question

i have 2 more minutes please help me

Answer 1

Answer:

487 m

Step-by-step explanation:

∠A = 65° + 12° = 77°

∠C = 90°

∠B = 13°   ( ∠A + ∠C + ∠B = 180°)

Sin∠A = Perpendicular / Hypotenuse

=> Sin77° = BC/ AB

=> BC = AB Sin77°

AB = 500 m

=> BC = 500 Sin77°

=> BC = 500 * 0.974

=> BC = 487

Length of BC = 487 m

option C is correct answer
