Answer: x= 19.5
(4x+12) = 90
Step-by-step explanation:
Notice the denoted right angle at the very top left. This means those intersecting lines are perpendicular forming 90 degree angles. All right angles are equal in measure so all 4 angles at the top are 90 degrees. We can then use corresponding angles to know that all of the bottom 4 angles are also 90 degrees. Now we can solve for x. (4x+12) =90. 4x= 78. X= 19.5
Answer:
20m+60
