Answer 1

Answer:

x+25°+35°+45°=180°[linear pair]

x+105°=180°

x=180-105=75°

therefore, x=75°ans.

Answer 2

Step-by-step explanation:

let,AB be the straight line and <ACD = x, <DCE = 25°, <ECF = 25° and <FCB = 45°

to find: value of x

since AB is a straight line

therefore

<ACD + <DCE + <ECF + <FCB = 180° (linear pair)

x + 25° + 25° + 45° = 180°

x + 95° = 180°

x = 180° - 95°

therefore, x = 85°
