given:
angle A+is 41 degrees
side c=61m+
side b=28m

a=sqrt%28b%5E2%2Bc%5E2-2bc%2Acos%28A%29%29
a=sqrt%2828%5E2%2B61%5E2-2%2A28%2A61%2Acos%2841%29%29
a=sqrt%28784%2B3721-2578.087926041%29
a=sqrt%281926.912073959%29
a=43.9m

angle B

B=cos%5E-1%28%28a%5E2%2Bc%5E2-b%5E2%29%2F%282ac%29%29

B=cos%5E-1%28%2843.9%5E2%2B61%5E2-28%5E2%29%2F%282%2A43.9%2A61%29%29

B=cos%5E-1%284864.21%2F5355.8%29

B=cos%5E-1%280.9082135255237312%29

B=24.7404°


angle C

C=180-%28A%2BB%29°

C=180-%2841%2B24.7404%29°

C=114.2596°
