# tap the picture and see the full question and please tell me how to do this please fast it's very urgent

The below step will help you construct an angle of $22\frac{1}{2}\xb0$

1. Draw a line PQ with any length. Draw an arc of some radius, taking P as its centre which intersects PQ at R.

2.Taking R as a centre and with the same radius as before, draw an arc intersecting the previously drawn arc (refer figure). Mark the point as S.

3. Taking S as a centre and with the same radius as before draw an arc intersecting the arc at T (refer figure).

4. Taking S and T as centre draw an arc of the same radius to intersect each other, mark the point as U.

5. Join PU with a dotted line, such that it intersects the arc at point V (refer figure).

6. From R and V draw arcs with a radius more than $\frac{RV}{2}$ to intersect each other and mark the point as W. Join PW with a dotted line.

7. Let it intersect the arc at X (refer figure). Now Take X and R as centre and radius more than $\frac{RX}{2}$ , draw arcs to intersect each other. Mark the point as Y.

8. Join PY

$\angle YPQistherequiredangle,22\frac{1}{2}\xb0$
