Question

1.
In the given figure l l| m find the value of x.​

Answer 1

Answer:

82 = 40 +x

Step-by-step explanation

82 = exterior of 40 and x {corresponding angles}

82 = x+40 {exterior angle property}

x = 82-40

x = 42

Answer 2

Answer:

42

Step-by-step explanation:

Naming

let angle 82° be A

angle X° be B

angle 40° be C

now,

Angle OAM = BOL = 82°

Angle BOL + BOC = 180

so, Angle BOC = 180-82= 98°

NOW in a triangle sum of all angle = 180°

so X = 180-40-98

X = 42°
