Question

correct answer of this question.​

Answer 1

Answer:

x will be 80 (verticaly opp. angle)

divide 180 by 80 u will get 100

and now you can take both Y as 50-50

or any with has there sum to 100

Step-by-step explanation:

Answer 2

Answer:

x = 80° & y = 50°

Step-by-step explanation:

TO FIND:

Value of x and y of the following diagram given,

SOLUTION:

let the value of 80° be ∠a

so, ∠a = ∠x   (vertically opposite angles)

As this is an isosceles triangle,

ATQ,

∠x + ∠y + ∠y = 180°    (angle sum property)

=> ∠x + 2∠y = 180°  

=> 80° + 2∠y = 180°  

=> 2∠y = 180° - 80°

=> 2∠y = 100°

=> ∠y = 100°/2

=> ∠y = 50°

Therefore, the value of x & y are 80° and 50° respectively.
