The perimeter of triangle ABC is 363cm, where AB = 75, BC = 1 / 3, 27

The perimeter of triangle ABC is 363cm, where AB = 75, BC = 1 / 3, 27


The perimeter of triangle ABC is 363cm, which is 11 √ 3
AB = root 75, which is 5 √ 3
BC = 1 / 3 radical 27, that is √ 3
So AC = 11 √ 3-5 √ 3 - √ 3
=5√3



The degree of two acute angles in isosceles triangle (non right triangle) is 1:2, so what is the maximum acute angle?


This is a common sense problem, there are only two cases of 1:2, one is right angle isosceles, the other is 72 degrees, 72 degrees, 36 degrees. If you want to set any angle in the process, you can use the proportional equation
