Construct angles of given measurement with a protractor – 35°, 52°, 110° and 138°. Construct a copy of ∠ABC and ∠PQR: Draw ∠ABC = 81° and draw its line of symmetry Draw ∠PQR = 125° and divide it into 4 equal parts.

In the figure (not to scale) AB = CD, angle DAP = angle DPA and A,B,C,D are concycli. If angle ADC = 80°, then find angle ACD.

Solve : 2^(x+2)+2^(x-1)=9
