Solve the Right Triangle $$b = 264.5 \mathrm {~m} , c = 390.5 \mathrm {~m}$$

question 12

Multiple Choice

Solve the right triangle. Round your answer to the appropriate number of significant digits. $$b = 264.5 \mathrm {~m} , c = 390.5 \mathrm {~m}$$

• A) \(a = 390.5 \mathrm {~m} , \angle A = 42.64 ^ { \circ } , \angle B = 47.36 ^ { \circ }\)
• B) \(a = 264.5 \mathrm {~m} , \angle A = 27.66 ^ { \circ } , \angle B = 62.34 ^ { \circ }\)
• C) \(a = 287.3 \mathrm {~m} , \angle A = 38.74 ^ { \circ } , \angle B = 51.26 ^ { \circ }\)
• D) \(a = 287.3 \mathrm {~m} , \angle A = 47.36 ^ { \circ } , \angle B = 42.64 ^ { \circ }\)
• E) \(a = 484.8 \mathrm {~m} , \angle A = 47.36 ^ { \circ } , \angle B = 42.64 ^ { \circ }\)

Definitions:

Atrial Fibrillation

A heart rhythm disorder characterized by rapid and irregular beating of the upper chambers of the heart, known as atria.

Ventricular Fibrillation

A life-threatening heart rhythm that results in rapid, erratic electrical impulses from the ventricles, leading to inefficiency in blood circulation.

Premature Ventricular Contractions

Early heartbeats originating from the ventricles of the heart, experienced as a palpitation.

Tricuspid Valve

A valve in the heart between the right atrium and right ventricle that prevents backflow of blood during ventricular contraction.
