Ответ:

∠АОВ = 75°

∠ОАВ = ∠ОВА = 52,5°

∠СОВ + ∠АОВ = 180°

Пусть ∠АОВ = х, тогда ∠СОВ = (х+50)

х + х + 50 = 180

2х = 130

х = 75°

∠АОВ = 75°

ΔАОВ - равносторониий (АО = ОВ - радиусы)

соответственно

∠ОАВ = ∠ОВА = (180 - 75) : 2 = 52,5°

The poet is about to come down from the pedestal and come to us. He holds his head erect and proud , but nothing in it suggests arrogance and affectation . His live a little sad eyes look at " tribe young , unknown " - to us . But the poet's thoughts about those who look at him , walking in the park. It seems that the poet is in creative thinking : on the forehead appear the wrinkles on the lips light pacified half-smile - a thought about something else . Perhaps the poet reflects on his homeland, the role of creativity in people's lives . Maybe it creates a new poem . But the whole look - the image of a creative , inspired man. His clothes are modest, common in the 19th century. On his coat draped over a long cloak which Draped .
