Answer :-
Given :
- x = 25°
- ∠AOC = (2y + 5)°
- ∠BOC = 3x°
To find :
- The value of y.
Solution :
If x = 25°, then ∠BOC (3x°) will be = (3 × 25)°
= 75°
We know that,
∠AOC + ∠BOC = 180°
[180° is a straight angle, we can see AOB as a straight angle in the above image. Hence, the value of ∠AOC + ∠BOC will be equal to 180°.]
According to question,
=> (2y + 5)° + 75° = 180°
=> 2y + 5° + 75° = 180°
=> 2y + 80° = 180°
=> 2y = 180° - 80°
=> 2y = 100°
=> y = (100/2)°
.°. y = 50°
Hence, the value of y will be 50° respectively.
