In a triangle, one of the angle measures 70°

and the remaining two angles are equal

Find the measure of the two angles.

the two angles are 55° each

Step-by-step explanation:

Let the two equal angles be y each

Therefore,

70° + y + y = 180°

Collect like terms

2y = 180 - 70

2y = 110

Divide both side by the coefficient of y i. e 2

y = 110/2

y = 55°

Therefore, the two angles are 55° each
