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°.

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
