Answer:

x ≈ 19.2 units

Step-by-step explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , then

x² + 19² = 27²

x² + 361 = 729 ( subtract 361 from both sides )

x² = 368 ( take square root of both sides )

x = \sqrt{368} ≈ 19.2 ( to the nearest tenth )

Answer:

x = 33

Step-by-step explanation:

a {}^{2}  + b {}^{2}  = c {}^{2}  \\ 27 {}^{2}  + 19 {}^{2}  = c {}^{2}  \\ 729 + 361 = c {}^{2}  \\ 1090 = c {}^{2}  \\  \sqrt{1090 }  =  \sqrt{c {}^{2} }  \\ c = 33

10 - |3n - 2| = -9<br><br>please help :D​
lapo4ka [179]

Answer:

n =7 or n = -17/3

Step-by-step explanation:

10 - |3n - 2| = -9  (subtract 10 from both sides)

- |3n - 2| = -9 - 10

- |3n - 2| = -19   (multiply both sides by -1)

|3n - 2| = 19

(3n - 2) = 19 or (3n - 2) = -19

For (3n - 2) = 19,

3n - 2 = 19

3n = 21

n =7 (answer)

For (3n - 2) = -19,

3n - 2 = -19

3n = -17

n = -17/3 (answer)
