Question

answer please send correct answer and clear explanation​

Answer 1

Step-by-step explanation:

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

Answer 2

Step-by-step explanation:

Given,

Exterior angle of the triangle = 140°

Internal angles are equal

Solution,

For calculating the three interior angles of the triangle we have to calculate the value of the adjacent interior angle with the given exterior angle.

We know, exterior angle + interior angle = 180°

So, interior angle = (180° - 140°) = 40°

Now,

The sum of other two interior angles = 180° - 40° = 140°

So, the value of other two interior angles = (140°/2) = 70°

Hence,the three interior angles of the triangle is 40°,70°,70°.
