Solve the right triangle.
-a = 2.6 in., A = 49.8°, C = 90° Round values to one decimal place.
A)b = 2.2 in., B = 40.2°, c = 3.4 in.
B)b = 4.0 in., B = 40.2°, c = 4.8 in.
C)b = 4.0 in., B = 40.2°, c = 3.4 in.
D)b = 1.1 in., B = 40.2°, c = 2.8 in.

To solve the right triangle, we can use trigonometric ratios. Since angle C is 90°, angle B = 180° - 90° - A = 40.2°. Using the sine rule, sin(A)/a = sin(B)/b, we can find b ≈ 2.2 in. Using Pythagoras' theorem, c = sqrt(a^2 + b^2) ≈ 3.4 in.
