Answer:
square of longest side ≠ the sum of the squares of the other two sides
It's not a right triangle
Step-by-step explanation:
The converse of the Pythagorean Theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
square of longest side: 12 12² = 144
the sum of the squares of the other two sides: 8² + 10² = 164
Answer:
80 degrees

Answer:
The missing digits are 3 and 1.
Step-by-step explanation:
6+3÷3-1=2
9÷3-1=2
3-1=2
Let,
digital cameras be "x"
video cameras be "y"
Now,
According to the question,
5x + 3y = $3,213..................................................equation (1)
y = 4x..................................................................equation (2)
Taking equation (1)
5x + 3y = $3,213
Substituting the value of "y" from equation (2), we get,
5x + 3(4x) = $3,213
5x + 12x = $3,213
17x = $3,213
x = $3,213 / 17
x = $189
Taking equation (2)
y = 4x
Substituting the value of "x", we get,
y = 4 ($189)
y = $756
Now,
John buys a digital and a video camera. So, it costs him ($189 + $756) = $945
