The perimeter is the sum of the three sides.
Subtract the length of the hypotenuse for the sum of the 2 sides:
60 - 26 = 34 cm
The Pythagorean theorem is a^2 + b^2 = c^2
Where a and b are the sides and c is the hypotenuse.
So we know a^2 + b^2 = 26^2
26^2 = 676
We also know a^2 +b^2 = 34 cm
Now a^2 +(34-a)^2 = 676
Factor:
a^2 + a^2-68a+1156 = 676
2a^2 -34a +480 = 0
Divide by 2:
a^2 - 17a +240 = 0
Factor:
a(a-10) - 24(a-10) = 0
a =10
b = 34 - 10 = 24
The sides are 10 cm and 24 cm
Answer:
The purpose of solving this problem is to determine what 9% of 891 is. One common real life problem where a solution like this may be helpful include calculating how much tip to leave at a restaurant. Solving this problem requires two simple math operations that you can perform on any calculator. The first step is a division and the second step is a multiplication. Here's a cool tip though, you can actually reverse the order of these operations and the result will be the same! Here are the steps:
Step 1: Divide 891 by 100
In this case, the number that we are "comparing" to 100 is 891, so we must first normalize the number by dividing it by 100. The operation we have to solve is this:
891
100
=
891
÷
100
=
8.91
Step 2: Multiply 8.91 by 9 to get the solution
Now that we have our normalized number, 8.91, we just have to multiply it by 9 to get our final answer. The forumla for this is obviously quite simple:
8.91
×
9
=
80.19
That's all there is to it! Note that you can replace these values with new ones from any similar problem.
