Awnser asap which pair of angles has congruent values for the sin x° and the cos y°? (5 points) 18°; 18° 18°; 162° 18°; 72° 18°; 108°

18°; 72° are the  pair of angles has congruent values for the sin x° and the cos y°.

Option C is correct.

Step-by-step explanation:

Given the pair of angles

we have to choose the pair which has congruent values for the sin x° and the cos y°

As all the trigonometric ratios are positive in first quadrant and

That implies the pair of angles which are complementary has congruent values for the sin x° and the cos y°

Option A: 18°; 18°

Not complementary therefore does not have congruent values for the sin x° and the cos y°

Option B: 18°; 162°

Not complementary therefore does not have congruent values for the sin x° and the cos y°

Option C: 18°; 72°

Complementary therefore has congruent values for the sin x° and the cos y°

Option D: 18°; 108°

Not complementary therefore does not have congruent values for the sin x° and the cos y°

Therefore option C is correct.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
