What is the length of a hypotenuse of a triangle if each of its legs is 4 units

Step-by-step explanation:

Using Pythagorean Theorem:

=>

Where c is hypotenuse, a is base and b is perpendicular and ( a, b = 4)

=>

=>

=>

Taking sqrt on both sides

=> c = 5.7 units

i dont really.know

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
