Solve the right triangle.
-A = 19° 17´, c = 287 ft, C = 90° Round side lengths to two decimal places, if necessary.
A)B = 70° 42´, a = 97.98 ft, b = 272.1 ft
B)B = 70° 43´, a = 94.21 ft , b = 270.01 ft
C)B = 71° 42´, a = 94.78 ft, b = 266.9 ft
D)B = 70° 43´, a = 94.78 ft, b = 270.9 ft

Angle B is 70° 43' (since B = 90° - A), a = c * sin(A) = 287 * sin(19° 17') = 94.78 ft, and b = c * cos(A) = 287 * cos(19° 17') = 270.9 ft.
