Which pair of angles have congruent values for the sin x° and the cos y°? A. 42°; 42°
B. 42°; 48°
C. 42°; 138°
D. 42°; 132°

There are different kinds of angles. The pair of angles have congruent values for the sin x° and the cos y° is 42; 48.

Congruent angles are regarded as a type of angles that is known to have all sides equal measure.

Two angles are said to be congruent if both sides and angles are of said to b equal measure.

not that sin x  = cos (90-x)

therefore,  sin 42 = cos(90-42) = cos 48

Conclusively, option B is correct

B. 42; 48

Explanation:

sin x  = cos (90-x)

eg sin 42 = cos(90-42) = cos 48

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
