If the legs are length a and b and hyptonuse is c then
a²+b²=c²
so
if the legs are 20 and 21 and the hypotnuse is x then
20²+21²=x²
400+441=x²
841=x²
29=x
Answer:
9 x 3 = 27

Step-by-step explanation:
An easier way to do this is to make the fractions improper fractions.
3 1/6 can be rewritten as 19/6. 1 4/6 can be rewritten as 10/6. (Multiply the denominator by the number at its side, and add it to the numerator).
2 3/6 is 15/6.
Subtract 10/6 from 19/6.
19/6-10/6=9/6.
9/6 is not 15/6, therefore she did not use 2 3/6 yards of fabric.
Two figures<span> that have the same shape are said to be </span>similar<span>. When two </span>figures<span> are </span>similar<span>, the ratios of the lengths of their corresponding sides are equal. We calculate as follows:
3.9 / 1.3 = 9.6 / b
b = 9.6 x 1.3 / 3.9
b = 3.2</span>
