Question

FIND INNER ANGLE X= ?​

Answer 1

Answer:

X=69. ...................

Answer 2

Answer:

GIVEN :

Angle JKM = 146

Angle KLM = 77

Angle LMK = X

TO SHOW :

Angle LMK = ?

SOLUTION :

angle LKM + JKM = 180  (Linear pair)

angle JKM = 146  

Then LKM + 146 = 180

LKM = 180 - 146

LKM = 34

In Triangle LKM,

Angle KLM + LKM + KML = 180 (Angle sum property)

put the values,

77 +  34 + X = 180

X =  180 - 111

X = 69    = ANSWER
