Автор ответа: tryryton

Сумма всех углов пересечения диагоналей прямоугольника 360°

Если один угол 49 то противоположен также 49 так как вертикальные углы равны
49+49=98
360-98=262 Два других угла между собой также равны как вертикальные

поэтому 262:2=131
Ответ: больший угол между диагоналями 131 градус
(вроде все сделал правильно)
