Answer:
(2 decimal places)
Step-by-step explanation:
Quadratic Formula:
-----------------------------------------------
Plug in values:
First value of x:
(2 decimal places)
Second value of x:
(2 decimal places)
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
