To solve this problem we need to be aware of the concepts of angles in a circle. Also we need to know what is a major angle and what is a minor angle.
That major part of an angle is equal to (360-minor part of the angle).
We know the total angle in a circle is 360°.
Here, ∠SKL=120+2x; ∠JKS=28° and ∠JKL=x+148.
Sum of all the angles will give us 360°.
According to question,
∠SKL+∠JKS+∠JKL=360°
⇒(120+2x)°+28°+(x+148)°=360°
⇒3x+296°=360°
⇒3x=360°-296°
⇒x=
∴ x=21.3
Hence, the value of x is 21.3 in the given problem.
