Question

answer the following

Answer 1

Step-by-step explanation:

From the fig.

=> 2x - 25° = 115° (Vertically Opposite Angles)

=> 2x = 140°

=> x = 70°

Also,

=> 115° + y° = 180° (Linear Pair)

=> y = 65°

Hope you've understood the solution.

Answer 2

2x-25°=115°(vertically opposite angles)

2x=115+25

2x=140

x=140/2=70°

115°+y°=180°(linear pair)

y°=180-115=65°

x=70°

y=65°
