In the figure m(arc LN) = 110°,
m(arc PQ) = 50° then complete the following activity to find ∠LMN.
∠ LMN = `1/2` [m(arc LN) - _______]
∴ ∠ LMN = `1/2` [_________ - 50°]
∴ ∠ LMN = `1/2` × _________
∴ ∠ LMN = __________
उत्तर
∠ LMN = `1/2` [m(arc LN) - m(arc PQ)]
∴ ∠ LMN = `1/2` [110°- 50°]
∴ ∠ LMN = `1/2` × 60°
∴ ∠ LMN = 30°
so , LMN = 30°
