Question

One of the angles of a triangle is 110 and the other two angles are equal. What is the measures of each of these equal angles

Answer 1

we have , interior angles of triangle =180°
=110°+x+x=180°
=110°+2x=180°
=2x=180°-110°
=2x=70°
=x=70/2
x=35°
then the angles are 110°,35°,35°

Answer 2

we know sum of all 3 angles of a triangle = 180 degree

If 1 angle = 110

sum of other two angles = 180 -110 = 70

If both angles are equal their measure will be = 70 / 2 =35 degree


Hence the 3 angles are 110 , 35 ,35 degrees.
