*brainliest goes to the first correct answer* what is the value for y? enter your answer in the box.

2x =50 since it is an isosceles triangle

x =25

the sum of all angles in a triangle is 180

5y + 10 + 50 + 2x=180

5y + 10 + 50 +50 =180  because  2x = 50

combine like terms

5y +110 = 180

subtract 110 from each side

5y = 70

y = 14

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.
