A right triangle has angles A and B as complementary angles. The measure of angle A is 8 more than the measure of angle B. What is the measure of angle A?
A) A = 94 degrees
B) A = 86 degrees
C) A = 41 degrees
D) A = 53 degrees
E) A = 49 degrees

In a right triangle, the sum of angles A and B is 90 degrees since they are complementary. Let B = x, then A = x + 8. The equation is x + (x + 8) = 90. Solving for x gives x = 41, so A = 41 + 8 = 49 degrees.
