$\begin{gathered}\small\green{{{\fcolorbox{lightgreen} {lightgreen}{ {☑verified \: answer}}}}}\\\end{gathered}$$\green{\fcolorbox{green}{red}{\large{\fcolorbox{blue}{lime}{{\fcolorbox{white}{white}{☑verified answer✯}}}}}}$${\huge{\red{\boxed{\green{\boxed{\blue{\boxed{\orange{\boxed{\pink{\boxed{\mathcal\purple{₳₦₴₩ɆⱤ}}}}}}}}}}}}}$$\pink{▬▬▬}$$\red{▬▬▬}$$\green{▬▬▬}$$\blue{▬▬▬}$$\orange{▬▬▬}$

We know that, in laws of reflection, the angle of incidence (x) is always equal to the angle of reflection (x). Since, AOB is a straight line. Hence, the value of x is 40°.

∠AOB = 180° 50° + x + x + 50° = 180°

(∴sum of all angles lies on the same side of aline is 180°)

2x + 100° = 180°

2x = 180° – 100°

2x = 80°

x=80°/2

x = 40°

Hence, the value of x is 40°.

Answer 2

• We know that, in laws of reflection, the angle of incidence (x) is always equal to the angle of reflection (x). Since, AOB is a straight line. Hence, the value of x is 40°.

Angle AOB = 180° 50° + x + x + 50° = 180°

(∴sum of all angles lies on the same side of aline is 180°)

2x + 100° = 180°

2x = 180° – 100°

2x = 80°

x=80°/2

x = 40°

Hence, the value of x is 40°.
