Solve the triangle. A = 50degree, B = 20degree, a = 8 Determine the value of C. C = (Round to the nearest whole number as needed.) Determine the value of b. b = (Round to two decimal places as needed.) Determine the value of c. c = (Round to two decimal places as needed.)
Solution
we know A+B+C=180
C=180-A-B = 180-50-20 = 110
from sine rule
a/sinA = b/sinB = c/sinC
b = asinB/sinA = 8*sin20/sin50 = 3.57
c = asinC/sinA = 8*sin110/sin50 = 2.91
