The exteriour angle obtained on producing the base of a triangle both the ways are 121º and 104º. What is the measure of the largest angle of the traingle?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 76º
The interior angles corresponding to their interior angles be , (180 - 121) and (180 - 104)
The two interior angles of the triangles are 59 and 76.
Third interior angle = 180 - 59 - 76 = 45°.
The largest interior angle will be 76°.
