Larger angle #hatA = 155^@#

For two angles to be supplementary, sum of these two angles equals #180^@#.

Let the two angles be #hatA, hatB#

Given #hat A + hatB = 180^@#

Also #hat A = ((6 * hatB )+ 5)^@#

#i.e. ((6 * hatB )+ 5) + hatB = 180#

#7*hatB = 180 - 5 = 175#

#hatB = 175 / 7 = 25^@#

Hence larger angle #hatA = 180 - 25 = 155^@#
