In a triangle of ABC B corner = 45 degrees, and the corner And is 20 degrees less, than S. Naydite's corner a-degree measure of a corner And yes define a type of a triangle of AVS. Pomogiiiite, pozh, if it works, that is desirable the equation: 3

Let's present that About it x, and And it x-20 Since the corner In that from 180-45=135 X+ (x +20)=135 X=155/2 X=77°3 " 77 "°3-20=57 °3 " } This acute triangle is already known to us
