In triangle ABC, it is known that a=60 b=70 A=38 degrees, find B and C (accurate to 1 degree

A divided by sinA is equal to b divided by sinB, thus calculating the angle of B, and then calculating the angle of C.

A triangle is a closed figure composed of three line segments in the same plane that are connected end to end in sequence. It is the basic figure of geometric patterns.

Triangles are divided into ordinary triangles (three sides are not equal) and isosceles triangles (an isosceles triangle with unequal waist and base, an isosceles triangle with equal waist and base is an equilateral triangle); According to angles, there are right triangles, acute triangles, obtuse triangles, etc.
