Julie Chapman · Answer 1

115 degrees

Step-by-step explanation:

for all triangles, the sum of all their angles is 180 degrees so ...

180-40-25=115

so the third angle is 115

Silas Kennedy · Answer 2

Step-by-step explanation:

Let the third angle be x

Sum of all the angles of a triangle = 180°

25 + 40 + x = 180

65 + x = 180

x = 180 - 65

x = 115°
