Question

m and n are parallel to each other . Then find y.​

Answer 1

Answer:

Angle Y= 120°

Step-by-step explanation:

PROPERTY USED:

Sum of angle of triangle is 180°

Sum of angle on a line is also 180°

Answer 2

Answer:

angle Y =60°

Step-by-step-explanation:

IN TRIANGLE ∆ABC ,

angle X +125°=180°{supplemetary angles}

X=180°-125°

X=55°

NOW,

angle X +angle Y + 65°=180°{Angle sum property of a triangle}

55°+Y+65°=180°

120°+Y=180°

Y= 180°-120°

Y=60°

Therefore,

angle Y =60°
