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

Answer 1

Josiah Anderson

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#.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
