Answer:
$175
Step-by-step explanation:
100 divided by 8 is 12.5
12.5 x 14 is 175.
The angle measured from the normal to the mirror will be
.. arctan(14/11.5) ≈ 50.6°
Complement angles mean that the sum of them = 90°
Say one if them = X
then the 2nd will be 5X
X+5X =90°
6X = 90°
X = 90/6
X = 15°
Therefore,
the 1st angle X = 15°
the 2nd angle 5X = 15 ×5 = 75°
20/35 and 21/35. The common denominator is 35.
