Answer:
Step-by-step explanation:
Property of a right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
If the length of sides of the given triangle are 7mm, 14mm and 15mm.
(15)² = (7)² + (14)²
225 = 49 + 196
225 = 245
False
Therefore, the given triangle is not a right triangle.
Answer:
Step-by-step explanation:
-2x + 5y = -15
5x + 2y = -6
-10x + 25y = -75
10x + 10y = -30
35y = -105
y = -3
5x + 2(-3) = -6
5x - 6 = -6
5x = 0
x = 0
(0, -3)
