Question

A:- Two supplementry are in the angles ratio 5:3 find the angles.
B:- state sas congruence rule. ​

Answer 1

Answer:

let the two angles be 4x and 5x respectively.

Therefore, 4x+5x=180°

9x=180°

x=180/9=20°

4x= 4× 20= 80°

5x= 5×20= 100°

SAS criterion suggests that if two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of another triangle, then the triangles are congruent.
