Answer:

The third side has a length of 9

Step-by-step explanation:

The two sides of equal length can be represented as x, and x

The thirds side is five less that twice the length of the other sides can be represented as  2x - 5.

The perimeter is 23, so the sum of all 3 sides is 23, now we have..

x + x + 2x - 5 = 23          solve for x...

4x = 28

x = 7,

so two sides are 7, and 7, and the third side is

2(7) - 5

  14 - 5

   9

A right triangle has a hypotenuse of 155 centimeters and a leg of 124 centimeters. Which of these is the length of the other leg
riadik2000 [5.3K]

Answer:

a

Step-by-step explanation:

Using Pythagoras' identity on the right triangle

let x be the other leg to be found, then

155² = 124² + x²

24025 = 15376 + x² ( subtract 15376 from both sides )

8649 = x² ( take the square root of both sides )

\sqrt{8649} = x

Hence x = 93 cm ← length of other leg → a

3x - 1 = 3x + 1  

subtract 3x from both sides to get (-1 = 1).  This is a false statement so it is: CONTRADICTION

************************************************

4x - 11 = 7

add 11 to both sides and then divide both sides by 4 to get (x = \frac{18}{4} = \frac{9}{2}).  This statement is true only when x = \frac{9}{2} so it is: CONDITIONAL

*************************************************

2 - 8x = 2 - 8x

add 8x to both sides to get (2 = 2).  This is a true statement so it is: IDENTITY

*************************************************

x + 1 = -x + 4

add x to both sides, subtract 1 from both sides, and divide both sides by 2 to get  (x = \frac{3}{2} ). This statement is true only when x = \frac{3}{2} so it is: CONDITIONAL

Answer: B, A, C, A
