Объяснение:

Нехай один кут - 2х,  другий кут - х, а третій - 6х

2х+ х+ 6х= 90°

9х= 90°

х= 10° другий кут

2х= 2 * 10= 20° перший кут

3х= 3 * 10 = 60° третій кут

sricking: Спс
denkrivko00: звідки взялося 6x?
dyexfnf: один кут -2х, і він у 3 рази менший від третього, т.е третій у 3 рази більший значить 2х * 3= 6х
