The greatest common factor of 30 would be 30
Answer: " y = 30° " .
_____________________________________
<u>Note</u>: The sum total of the measure of all angles lying on a straight
line is 180°.
So; x + y + z = 180 .
Given: x = 2y ;
z = 3y ;
__________________
Find the value of: " y " ;
_______________________
Since: x + y + z = 180 ;
Substitute: "2y" for "x" ;
and: "3y" for "z" ;
_______________________
2y + y + 3y = 180 ;
6y = 180 ;
______________________
Divide EACH SIDE of the equation by "6" ; to isolate "y" on one side of the equation; and to solve for "y" ;
___________________________
6y/ 6 = 180 / 6 ;
y = 30 ;
____________________________
Let us check our work;
____________________________
2y + y + 3y = 180 ;
Substitute our solved value: "30" ; for "y" ; in the equation; to see if the equation holds true:
____________________________
2(30) + 30 + 3(30) =? 180 ?
____________________________
60 + 30 + 90 = ? 180 ?
____________________________
90 + 90 = ? 180 ? Yes!

x=76
y=4
I think that answer should be right. Since it is isosceles the base angles will be the same and the top angle is an angle bisector which means that the angle split on top has even splits. Since no other side lengths- or any lengths at that matter- are give, it is safe to assume that y=4.
