Answer: B. 9.8%
Step-by-step explanation:
Hi, to answer this question we have to use proportions
since 23.5 is the 100% = 23.5 inches /100 %
For 21.2 inches =21.2inches /x%
23.5/100 =21.2/x
Solving for x:
x = 21.2 / (23.5/100)
x = 90.2%
21.1 inches are 90.2% of 23.5 inches.
So, the percent decrease is:
100% - 90.21 % = 9.8 %

x = 52.5
The triangle on the left has 2 congruent sides, thus is isosceles
The base angles of an isosceles triangle are also congruent, thus
x = = = 52.5
