Measures of the angles are [tex]25.5^{\circ},124.5^{\circ},30^{\circ}[/tex]
According to the angle sum property of a triangle, sum of all the angles is equal to [tex]\boldsymbol{180^{\circ}}[/tex]
Let the measure of another angle be [tex]x[/tex]
As the measure of one angle is thirteen less than five times the measure of another angle,
Measure of one angle [tex]=5x-13[/tex]
Sum of measures of the two angle [tex]=140^{\circ}[/tex]
[tex]x+5x-13=140^{\circ}[/tex]
[tex]6x=153[/tex]
[tex]x=25.5^{\circ}[/tex]
[tex]5x-3=5(25.5)-3[/tex]
[tex]=124.5^{\circ}[/tex]
Measure of the third angle [tex]=180^{\circ}-25.5^{\circ}-124.5^{\circ}[/tex]
[tex]=30^{\circ}[/tex]
