solving oblique triangles

Question

solve the oblique triangle angle A=10 angle= B=10 angle C=? side A =? side b=? side c=10

Answer 1

since <A=10 and <B=10 then <C = 180 -10-10, <C=160

use the law of sines to find the missing sides:  sinA/a = sinB/b = sinC/c

so sin160/10 = sin10/a  which means 10sin10 = asin160

means 1.73648=asin160

divide both sides by sin160 and a=5.08

since angle A and B are equal then it is an isosceles triangle which then means sides a and be are equal.

Final answer <C=160     side a=b=5.08

Answer 2

Angle c = 160

Answer 3
