Solve for x if the three angles of a triangle are: x, 45 degrees, and 5x degrees
Tcecarenko [31]

Answer: 22.5 degrees

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees.

So we can set up an equation to solve for x.

x + 45 + 5x = 180.

Combine like terms of x:

6x + 45 = 180

Subtract 45 from both sides:

6x = 135

Divide both sides by 6:

x = 22.5 degrees

What is the answer to this?
alexdok [17]

Answer:

  1. x < 2.5
  2. x > 2.5

Step-by-step explanation:

One way to do this is to try a number for x and see if it makes the inequality true. A suitable number here is x=0. This value of x is less than 2.5.

<h3>1.</h3>

For x=0, you have ...

  5 > -5 . . . . . true; the solution space is x < 2.5

__

<h3>2.</h3>

For x=0, you have ...

  -25 > -5(2.5)

  -25 > -12.5 . . . . . false; the solution space is x > 2.5

_____

<em>Alternate solution</em>

<h3>1.</h3>

Subtract 5:

  -4x > -10

Divide by -4

  x < 2.5

__

<h3>2.</h3>

Divide by -5:

  5 < x +2.5

Subtract 2.5

  2.5 < x

  x > 2.5
