Question

I need help on this, find the value of x

Answer 1

x=35

obtuse scalene triangle

Explanation:

All angles in a triangle add up to 180°.

`3x-5+x+10+x=180`

`5x+5=180`

`5x=175`

`x=35`

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.
