Question

9. The exterior andes ootamed on producing the base of a triangle both ways to
136" Find all the angles of the triangle​

Answer 1

Answer:

Step-by-step explanation:

From the adjacent figure, 

the exterior angle ∠ACD=136°

∴, ∠ACB=180°-136°=44°

the other exterior angle, ∠ABE=104°

∴, ∠ABC=180°-104°=76°

∴, ∠BAC=180°-(∠ABC+∠ACB)

              =180°-(76°+44°)

              =180°-120°

              =60°

∴, the angles of the given triangle are: 76°,60° and 44° Ans.
