113 is one number. 131 is another
137, 173
I think that's all of them.
You can check if you google 'list of primes'.
Hold on i'm not sure about 113 and 131 Is number 1 a prime number? I dont think it is , So that leaves us with only 137 and 173.
Ok since it’s a 45 45 90 right triangle then both sides equal 5. And to find x you do
A^2 +b^2=c^2
5^2 +5^2= c^2
25+25=c^2
50=c^2
Take the square root of both sides and you get X= 5 square root of 2 or 7.071(rounded)
To see how much she saved, you multiply 24.90 x 10 ÷ 100 (or to simplify it 24.90 ÷ 10) you should get 2.49, which you subtract from the original and get $22.41
