1. 30°

###### Advertisements

#### Solution

Steps of construction:

1. Draw a line segment AB.

2. With center A and any radius, draw an arc which intersect AB at C.

3. With center C and same radius, draw an arc which intersects previous arc at D.

4. With centers D and C and radius more than `1/2`DC ,draw arcs intersecting each other at

E

5. Join EA

∴ `∠`EAB = 30°
