Answer:
19/75
Step-by-step explanation:
---
Supplementary angles are two angles that when add equal 180 degrees.
The supplement of an angle is 180 - n.
n = 17(180 - n)
n = 3060 - 17n
n + 17n = 3060
18n = 3060
n = 3060/18
n = 170
so the unknown angle (n) = 170 degrees and its supplement = (180 - 170 = 10)......= 10 degrees.
The two points have the same y value, so it is a horizontal line. Between 5 and 10, the distance is 5.
You just divide 10 1/2 by 1 1/2 to get the length of the floor.
The answer is 7 tiles to reach the length of the floor.
Hope this helps!
