Use the image below to answer the following question. Find the value of sin x° and cos y°. What relationship do the ratios of sin x° and cos y° share? A right triangle is shown with one leg measuring 12 and another leg measuring 5. The angle across from the leg measuring 5 is marked x degrees, and the angle across from the leg measuring 12 is marked y degrees.

The answer is below

Step-by-step explanation:

Trigonometric identities are ratios used to show the relationship between the sides and angles in a right angled triangle. Some trigonometric identities are:

sinθ = opposite / hypotenuse; cosθ = adjacent / hypotenuse; tanθ = opposite / adjacent

From the image, let a be the hypotenuse, hence:

a² = 15² + 8²

a² = 225 + 64

a² = 289

a = 17

From the triangle:

90 + x + y = 180 (sum of angle in a triangle)

x + y = 90

It is stated that for a right angled triangle, if x + y = 90 (complementary angles) then:

sinx = cosy

To prove:

sinx = 8/17; cosy = 8/17. Hence:

sinx = cosy

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
