$\large \green{ \fcolorbox{gray}{black}{ ☑ \: \textbf{Verified \: answer}}}$

LM = MN

• (From figure)

∠MLN = ∠LNM = 50°

• Angle opp. to tge the equal sides are equal.

x + 50° + 50° = 180°

• Sum of Angle of Traingle is 180°

x + 100° = 180°

x = 80°

Answer 2

Answer: 80°

Step-by-step explanation:

As MN = ML

Triangle MNL is isosceles

according to the rule of isosceles triangle The angle corresponding to The two equal sides will be same as the angle MNL is 50 degree Angle NLM Will also be 50 degree

Now, SUM Of all the angles of triangle = 180 degrees

now

x degrees + 50 degrees + 50 degrees = 180 degrees

100 degrees + x degrees = 180 degrees

x degrees = ( 180 - 100 ) degrees

x degrees = 80 degrees

Have a great day :)
