Question 932635
Solve triangle ABC. (If an answer does not exist, enter DNE. Round your answers to one decimal place.)
b = 67, c = 38, A = 78°
B =____°
C =____°
a = ____
***
key:
angle: upper case letter
side opposite angle: lower case letter
..
Here are the steps to follow using Laws of Cosine and Sine:
a^2=b^2+c^2-2*b*c*cosA (solve for a)
{{{sinA/a=sinB/b}}} (solve for B)
C=180-(A+B)
