They will form the square as all angles will be 90
( one is given 90
tangents are too perpendicular to radius
by angle sum property 4th angle will be 90 )
adjecent sides are equal radius = radius
therefore it is square .
all sides in square are equal
therefore length of tangent will be too 5 cms.
Hope u understand it .
