Answer:
Ariel answer is wrong.
Step-by-step explanation:
Given that Ariel had done a Math problem for a triangle with sides
9,15 and 12. She concluded that these sides are not that of a right triangle.
To check whether Ariel is right:
Greater side = 15
Hence greatest angle will be opposite 15
Let us check pythagorean theorem
smaller sides are 9 and 12
Square and add them
9 square +12 square = 81+144 = 225 =15 square
We find that Pythagorus theorem is satisfied
Hence it is concluded that the triangle is right angled and Ariel was wrong
ABC is the silaged
Answer.
Please subtract
The answer is 3
A variable is a letter in the equation.
A, B, and C dont have variables... unless a question mark is considered a variable at your school (I dont consider it a variable).
D has an x in the equation, so D has a variable.
