Two angles, X and Y, are complementary. If cosX=1/2 is sinY?

sin y = 1/2

Step-by-step explanation:

complementary angles sum to 90°

The two acute angles of a right triangle are complementary.

On a right triangle the opposite side from one acute angle is the adjacent side of the other acute angle

cos x = adj/hyp = sin y

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
