We have,
A parallelogram RING, if ∠R=70o
Then, solve that,
∠I=?
∠N=?
∠G=?
We know that,
Adjacent angles of parallelogram is supplementary.
Then,
∠R+∠I=180o
70o+∠I=180o
∠I=180o−70o
∠I=110o
But we know that,
Opposite angles of parallelogram are equal.
Then,
∠R=∠N
70o=∠N
∠N=70o
And
∠I=∠G
110o=∠G
∠G=110o
Hence, this is the answer.
