Answer:

the sum of angles a triangle =180°

x in degrees

3x+4x+5x= 180°

12x=180°

x =15°

angle 3x° = 45°

angle 4x° = 60°

angle 5x° = 75°

Step-by-step explanation:

The actual measures of the angles in the triangle are 45 degrees, 60 degrees, and 75 degrees.

The sum of the angles in a triangle is always 180 degrees. We can set up an equation to find the values of x:

3x + 4x + 5x = 180

12x = 180

x = 15

Now we can substitute x back into the angles to find their actual measures:

3x = 45 degrees

4x = 60 degrees

5x = 75 degrees

Therefore, the actual measures of the angles in the triangle are 45 degrees, 60 degrees, and 75 degrees.
