1.) {Picture_6.png} Find the value of y.
Steps
Expanantion
36 + 9y = 90
Due to the fact that line A and Line B are perpendicular they equal 90 degrees
-36 -36
Subtract 36 to each side to solve for y.
9y = 54
Reduce
/9 /9
Divide each side by 9 to isolate y
y = 6

Explanation:
*Perpendicular lines are two lines that intersect to form a right angle.
*Perpendicular lines are represented with an upside "T". (Example: {Picture_5.png}
*A right angle is an angle that measures 90 degrees.
*All right angles are congruent
