Question

Two angles in a triangle are 40 and 95. List the 3rd interior and two exterior angles.

Answer 1

interior angle=45

two exterior angle= 140, 85

Explanation:

sum of all angles= 180

40+95+x=180

x=180-135

x=45, ie the third interior angle=45

two exterior angles be y, z respectively

y=180-40(linear pair)=140

z=180-95(linear pair)=85
