All the angles in a triangle equal 180 degrees.
So,
y+40+y+30= 180
2y+70= 180
2y= 110
Divide by 2.
y= 55
"A" is the answer.
I hope this helps!

Answer:
Similar states:
- They have the same geometric shape.
- Their corresponding sides are in proportion.
Given the statement: Pentagon JKLMN is similar to pentagon STUVW .
If NJ = 4 units WS = 3 units and JK = 5 units.
We have to find ST.
By definition of similar;
.
then;
Substitute the given values, to solve for ST;
By cross multiply we have;
Divide both sides by 4 we get;
Therefore, the value of ST = 3.75 units
