656565

Video Solution

Solution Steps

00:00 Find the empty angle
00:04 Draw the line extension
00:07 Mark the adjacent angles with unknowns B and A
00:11 Adjacent angles sum to 180
00:18 Isolate the unknowns
00:31 We don't have enough data to calculate the angles
00:36 Therefore there is no solution to the question

Answer

It cannot be calculated.
