Question

If the two angles of a triangle is 40 and 65 what will be the third angle

Answer 1

Answer:

Step-by-step explanation:

Sum of interior angles of a triangle=180

40+65+third angle=180

105+third angle=180

Third angle=180-105

Hence,third angle=75

Answer 2

Answer:

75

Step-by-step explanation:

a+b+c=180

lets take c=third angle

40+65+c=180

105+c=180

c=180-105

c=75
