The dimensions of one of the sails on a sailboat are 9 feet, 12 feet, and 15 feet. Is the sail a right triangle?
2 answers:
Answer:
yes
Step-by-step explanation:
Using the converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.
longest side = 15 , then 15² = 225
9² + 12² = 81 + 144 = 225
Thus the sail is a right triangle.
In order to test if it’s a right triangle, we can try to apply Pythagorean theorem, which is x^2+y^2=z^2

Answer:
The answer is 457
Step-by-step explanation:
You set up an equation as

a+c=783
c= child
a= adult
