Angle AOB = x + 4
Angle BOC = 3x + 2
Angle AOC =90° ( ∵ it is right angle )

The value of "x".


Since it is right-angle,

x + 4 + 3x + 2 = 90°
x + 3x + 4 + 2 = 90°
4x + 6 = 90°
4x = 90° - 6
4x = 84°
x =

x = 21°

Now, the two angles are
∠ AOB = x + 4 = 21° + 4 = 25°
∠ BOC = 3x + 2 = 3 x 21° + 2 = 63° + 2 = 65°

➡ ∠ AOB + ∠ BOC = ∠ AOC
➡ 25° + 65° = 90°
➡ 90° = 90°
➡ L. H . S. = R. H. S
Hence verified. ✔
