Question

in The given figure find the value of Y
​

Answer 1

Answer:

according to the question,

3y + 40° + 2y = 180°. ( straight line property)

=> 5y = 180 - 40

=> y = 140/5

=> y = 28°

so,

the angles are

3y = 3*28 = 84°

and

2y = 2*28 = 56°

and 40°

$.$

Answer 2

Answer:

3y+40°+2y=180° (Linear pair)

5y+40°=180°

5y=180°-40

5y= 140°

y= 140°/5

y= 28°
