In triangle abc if a-b 120 and r 8r
WebProblem 1 A triangle ABC has angle A = 106 o, angle B = 31 o and side a = 10 cm. Solve the triangle ABC by finding angle C and sides b and c.(round answers to 1 decimal place).. Solution to Problem 1: Use the fact that the sum of all three angles of a triangle is equal to 180 o to write an equation in C. A + B + C = 180 o; Solve for C. C = 180 o - (A + B) = 43 o WebAnswer (1 of 4): In Case of Similar Triangles, Ratio of Corresponding Sides are Equal. Therefore, (XZ)/(YZ)= (AC)/(BC)==> XZ= 7×(9/5) XZ= 12.6 cm
