Answer:
y = 7
Step-by-step explanation:
If SQ is bisector then (5y+3)=(7y-11)
(5y+3) = (7y-11)
5y+3 = 7y-11
3 = 2y - 11
14 = 2y
2y = 14
y = 7
SSS is side-side-side
SAS is side-angle-side
They are used to prove a statement
Y(x-1)=z divide both sides by y
x-1=z/y add 1 to both sides
x=(z/y)+1 or more neatly
x=(z+y)/y
Divide the number that islf can divide by like 2 or 3 or 4 for exaples
