80 + 180 - 105 + x = 180
x = 25 hope it helped you
Answer:
Step-by-step explanation:
In∆ABC
By angle sum property ( sum of all angles is 180°)
angle ABC+ angle BAC+angleBCA=180°
45°+60°+angle BCA=180°
AngleBCA=180°-105°
AngleBCA=75°
AngleBCA=angleDCE
[Vertically opposite angles]
angle DCE=75°
NOW,
In∆CDE
By angle sum property
Angle C+angleD +angle E=180°
75°+80°+x=180°
x=180°-155°
x=25°
