Question

an exterior angle of a triangle is 130°and one of the interior opposite angle is 45° the other two angles?​

Answer 1

Answer:An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Ext. Angle = 130

Interior opp. Angle1 = 45

Hence the other one is 130–45 = 85

We know the measure of two angles, we need the third one.

Measure of the third angle = 180 - (45+85) = 50

Answer: The other two angles are 50 & 85

Step-by-step explanation:

Answer 2

Answer:

one of the opposite angle is 85° and the remaining one angle is 50°.

Step-by-step explanation:

As we know that exterior angle of a triangle is equal to the sum of it's opposite interior angles of the triangle..

Therefore , 45°+ x = 130°

x = 85° ..

Also we know that , sum of all the angles of triangle is 180° .

Therefore , 45° + 85° + y = 180°

y = 50°..
