Answer:
x = 89
Step-by-step explanation:
Inscribed Angle = 1/2 Intercepted Arc
45 = 1/2 AB
90 = arc AB
Angle Formed by Two Chords
= 1/2 ( sum of Intercepted Arcs)
x = 1/2 ( 88+ 90)
x = 1/2 (178)
x = 89
I assume you need the difference between the percentages,
if
132 mil...........................100%
9.2 mil............................x
x=(9.2 mil * 100)/132= 6.96%
142 mil...........................100%
13.4 mil..........................y
y=(13.4 *100)/142= 9.43%
the difference is
9.43-6.96=2.47 %
X=-7
I'd be happy to help if you need an explanation:)
To calculate the area you would do L*w=a² and that is how much ft of rug you will need
