DIAGRAM A)
X = 95
SOLUTION :-
A + B + C = 180.........sum of the all angles of triangle
X + 40 + 45 = 180
X + 85 = 180
X = 180 - 85
X = 95°
X = 95°
DIAGRAM B)
X = 27
SOLUTION :-
M + N + O = 180.....sum of the all angles of triangle
3X- 17 + X + 40 + 2X - 5 = 180
6X + 18 = 180
6X = 180 - 18
6X = 162
X = 162/6
X = 27
X = 27°
