Sagot :

Answer:

x=35

obtuse scalene triangle

Step-by-step explanation:

All angles in a triangle add up to 180°.

[tex]3x-5+x+10+x=180[/tex]

[tex]5x+5=180[/tex]

[tex]5x=175[/tex]

[tex]x=35[/tex]

So, x=35.

When we plug in x to each angle, we see that the 3x-5 angle is above 90°, and all of the angles are different. So, this is an obtuse scalene triangle.
