The largest angle is $115^circ$

The total sum of the angles in a triangle is 180

so $(8x-5)+2x+(3x-10)=180$

$=>13x-15=180$

$=>13x=195$

$=>x=15$

Therefore the angles are $115^circ, 30^circ$ and $35^circ$ , The largest of which is $115^circ$ .

The measures of three angles of a triangle are given by (8x- 5)° , (2x)°,(8x- 5)° , (2x)°, and (3x - 10)°(3x - 10)°. What is the measure of the largest angle?
