Which pair of angles has congruent values for the sin x° and the cos y°?

35°; 55°
35°; 145°
35°; 70°
35°; 35°

a? or b? or something else?

35°; 55°

Step-by-step explanation:

Suppose,

Hence, x and y must be complementary angles.

∵ 35° + 55°  = 90°

35° +  145°  = 180° ≠ 90°

35° + 70°  = 105° ≠ 90°

35° +  35° = 70° ≠ 90°

Therefore, the pair of angles would be 35°; 55°.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
