solve for the remaining sides and angles if possible As in t

solve for the remaining side(s) and angle(s) if possible. As in the text, (, a), (, b) and (, c) are angle-side opposite pairs. . = 42 , a = 17, b = 23.5

Solution

(, a), (, b) and (, c) are angle-side opposite pairs. .

= 42 , a = 17, b = 23.5

a/sin = 23.5/sin

sin = 23.5*sin42/17 =0.9249

= 67.66 deg

= 180 - - = 180 -42 - 67.66 = 70.33 deg

c/sin = a/sin

c = sin70.33*17/sin42 = 23.92
