Determine the number of Wangles B 15 degree C 65 degree an

Determine the number of Wangles. B = 15 degree C. = 65 degree, and a = 19 1 triangle 2 triangles no triangle

Solution

As per the rules of geometry,

The sum of two angles of a triangle is always greater than the side of the third angle

Given B=15

C=65

Hence A= 180-B-C= 100

according to geometry, A>=B+C which is not possible with given measurements

hence no triangle is formed
