Which pair of angles has congruent values for the sin x and the cos y?
a) 42; 42
b)42; 48
c)42; 138
d)42; 132

The correct answer is option B,  42;48

Step-by-step explanation:

The congruent angles are complementary to each other and thus their sum shall be equal to 90 degrees

Let put x = 42 degrees in the equation, we get -

Thus the congruent values for sin x and Cos Y is 42, 48

a. -0.3 > -0.33
