Question

Geometry question- SOLVE FOR X.

Answer 1

Answer:

$x = 4$

Step-by-step explanation:

Step 1:  Solve for x

Since there are two parallel lines and one perpendicular line through the middle, that means that all of the angles are equal.  Therefore, we can make an equation 21x + 6 = 90 and solve for x

$21x + 6 - 6 = 90 - 6$

$21x / 21 = 84 / 21$

$x = 4$

Answer:  $x = 4$
