Question

if two angles of a triangle measure 35 and 68 then which of the following measures cannot be the measure of one of the exterior angles of the triangle?
(A) 103 (B) 112 (C) 136 (D) 145​

Answer 1

Answer:

b,c,d

Step-by-step explanation:

35+68 =103

so b,c,d is the answer

Answer 2

Answer:

136

Step-by-step explanation:

180 - 35 = 145[linear pair] (exterior angle 1)

180 - 68 = 112[linear pair] (exterior angle 2)

third side = 180 - (35 + 68) [angle sum property]

    = 180 - 103

    = 77

exterior angle 3 = 180 - 77[linear pair]

    = 103

                   exterior angles = 145 , 112 , 103

               leftover option = 136
