Question

В треугольнике АВС известно, что АВ=ВС и <АВС=126 градусов. Найдите <ВСА. Ответ дайте в градусах.

Answer 1

Tак как АВ=ВС, то треугольник АВС- равнобедренный, то по свойству равнобедренного треугольника угол BAC будет равен углу BCA.
 ВAC=BСA=180-126/2=54/2=27
Ответ:27

Answer 2

Triangle Angle Calculation

To find the angle ∠BCA in triangle ABC, where AB = BC and ∠ABC = 126 degrees, we can use the properties of isosceles triangles. In an isosceles triangle, the angles opposite the equal sides are also equal. Therefore, ∠BCA = ∠ABC = 126 degrees.

So, ∠BCA = 126 degrees.

This information is based on the properties of isosceles triangles, where the angles opposite the equal sides are equal.
