How to construct an angle of 25° using a protractor?

In the given figure (a), mark a point at 25 from 0 on the baseline PQ. Similarly, in figure (b), mark a point at 25 from 0 on the baseline QP. Name the marked point R. Remove the moon and using a ruler and pencil, join PTR in figure (a) and join R and 0 in figure (b). ZRPQ = 25° and ZRQP = 25°. Using the moon, construct the following angles: (i) ZABC - 359 (ii) ZPQR = 789 (iii) ZXYZ = 150°.
