Solution: Here, AB //PQ, so <ARQ + < PRQ = 180o                      [ sum of co-interior angles.] or, 80 + n = 180 or, n = 180 - 80 So, n  = 100o Again, RQ// BC, So, <ARQ = .....

Here, (sinA - cosA) 2 / [ sin 2 A - cos 2 A] = (sinA - cosA) 2 / ( sin A + cos  A)( sin A - cos  A)   [ using , a2 - b2 = ( a + b ) ( a - b ).] = (sinA - cosA)  / ( sin A .....
