Question

Yu-Xi draws a triangle with two angles measuring 79 degrees and 23 degrees.What is the measure, in degrees, of the third angle?

Answer 1

79+23=102
180-102=78
the third angle is 78 degrees

Answer 2

The Triangle Drawn by ,Yu-Xi,has measure of two angles ,79° and 23°.

All the Basic Learners who knows Math ,that,sum of Measures of three Interior angles of Triangle is 180°.

→79°+23°+Third Angle =180°

→102°+Third Angle =180°

→Third Angle =180° -102°

Third Angle =78°
