Answer:

C. 10

Step-by-step explanation:

Two sides of the right triangle are equal to each other, which is 5√2.

The third side is the hypotenuse length = x

We can use pythagorean theorem to find x.

Thus,

c² = a² + b²

Where,

a = 5√2

b = 5√2

c = x

Therefore:

x² = (5√2)² + (5√2)²

x² = 50 + 50

x² = 100

x = √100

x = 10

The length of a rectangle is 4 centimeters more than twice its width. If the perimeter of the rectangle is 86 centimeters , find
tensa zangetsu [6.8K]
P = perimeter = 2L + 2W = 86 cm.  Also, L = W + 4.  Subst. W + 4 for L, 

P = 2(W + 4) + 2W = 86 cm.  Then 2W + 8 + 2W = 86 cm, and 4W = 78 cm.

Finally solving for W, W = (78 cm)/4, or 19.5 cm.

If W = 19.5 cm, then L = W + 4 cm = 19.5 cm + 4 cm = 23.5 cm

The rectangle's dimensions are 19.5 cm by 23.5 cm.
