Answer: 0
Step-by-step explanation:
Step 1: factor left side of equation
y(5y^2-3y+8)=0
Step 2: set factors to equal zero
y=0 or 5y^2-3y+8=0
y=0
If line AB is parallel to line CD, and line CD is perpendicular to line EF, AB is perpendicular to line EF due to the perpendicular transversal theorem<span>,which says, if a line is perpendicular to another line, then it is perpendicular to the line parallel to the second line.
This theorem can be proved through the transversal postulate and theorems.</span>
The two triangles are similar :
1) the angle of QRS and VTU is the same
2) if you notice the length of VT and QR, QR is twice as VT. // same goes to the length of SR and UT.
