Find the length of the missing side. triangle with an 8 inch side and 12 inch side with a right angle 8.9 in. 104 in. 4 in 14.4
Mamont248 [21]

Given:

In a triangle, length of one side is 8 inches and length of another side is 12 inches, and an angle is a right angle.

To find:

The length of the missing side.

Solution:

In a right angle triangle,

Hypotenuse^2=Perpendicular^2+Base^2

Suppose the measures of sides adjacent to the right angle are 8 inches and 12 inches.  

Substituting Perpendicular = 8 inches and Base = 12 inches, we get

Hypotenuse^2=8^2+12^2

Hypotenuse^2=64+144

Hypotenuse^2=208

Taking square root on both sides, we get

Hypotenuse=\sqrt{208}

Hypotenuse=14.422205

Hypotenuse\approx 14.4

The length of the missing side is 14.4 inches. Therefore, the correct option is D.

A scale has a percent error of 7%. The scale reads the mass of a book as 450g. Which statement describes what the actual mass of
ozzi

Answer:

The actual mass of the book is between  481 . 5 g and 418 . 5 g.

Step-by-step explanation:

The mass of the book on the scale = 450 g

The percentage error in the scale = 7%

So, the actual mass of the book is 450 g ± 7%

Now, 7 % of  the mass 450 g = \frac{7}{100}  \times 450 = 31.5

⇒ 7% of 450 g = 31.5 g

Now, the Actual mass of the book =  450 g ± 31.5 g

450 g + 31.5 g   = 481 . 5 g

450 g - 31.5 g    = 418 . 5 g

Hence the actual mass of the book is between  481 . 5 g and 418 . 5 g.
