(i) It is given that
Perimeter of triangle =
cm
Ratio among sides =
Here the sum of ratios =
We know that
Length of first side =
cm
Length of second side =
cm
Length of third side =
cm
Therefore, the sides are
cm,
cm and
cm.
(ii) We know that
Sum of all the angles of a triangle =
Here the ratio among angles =
Sum of ratios =
So we get
First angle =
Second angle =
Third angle =
Hence, the angles are
