In trapezium HARE. EP and RP are bisectors of E and R respectively. find ∠HAR and ∠EHA.
Adjacent angles along a side of a trapezium are supplementary.
Hence, ∠R + ∠A = 180 ________(i)
Similarly, ∠E + ∠H = 180 ________(ii)
According to given data in question,
The complete ∠R = 2×30 = 60
And ∠E = 2×25 = 50
Because, EP and RP are bisectors of E and R respectively.
By Eq (i) and (ii),
∠A = 180-60 = 120
∠H = 180-50 = 130
