solve ∆ABC when a = 32 in, and A = 128°.​

Sagot :

Let's assume ∆ABC is an isosceles triangle.

(see photo to see the solution for measures of angles B and C.)

line segment b and line segment c's length cannot be determined due to lack of information. But if we assume that they were the legs of isosceles triangle, b=c.
