Question

****BRAINLIEST GOES TO THE FIRST CORRECT ANSWER****

Answer 1

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

Answer 2

the anwser to this is y=14
