16

Step-by-step explanation:

Use the property of 45 degree right triangles

c = a√2, where c- hypotenuse, a = legs

Top diagram

x = 5√2

Bottom diagram

x = 8√2(√2) = 16

The formula for percent error is:

((Approximate value - exact value) / exact value) x 100

1) 14-12 = 2

2/12 = 0.1666

0.166 x 100 = 16.7% (Rounded to nearest tenth)

2) 231 - 215 = 16

16/215 = 0.74419

0.74419 x 100 = 7.4419% ( Round as needed)

3) 17.1 - 16.5 = 0.6

0.6/16.5 = 0.36364

0.36364 x 100 = 3.6364% (Round off as needed)

4) 1081 - 1150 = -69

-69/1150 = -0.06

-0.06 x 100 = -6% = 6% error

2(3x-2)=14 pls help

Temka [501]

2(3x-2)=14

1) Distribute 2
(6x-4)=14
2) Add (4) one both sides
6x-4=14
6x+4=14+4
6x=18
3) Divide 6 one both sides
6x / 6 = 18 / 6
4) Solve
X=3

Hope it helps

The lengths of the legs of a right triangle are 5 centimeters and 10 centimeters. Which of the following measures is closest to

Svet_ta [14]

Hey there!

The length of the hypotenuse is about 11 centimeters.

To solve this, we use the formula $a^2+b^2=c^2$ , where $c$ is the hypotenuse leg and $a$ and $b$ are the other sides. So we can plug the numbers in to the formula:
