here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
