Answer 1

Answer:

bro. listen there are some properties in geometry.

• 90° = y ( reason:- vertically opposite angle )

• so, 90°+ x + x = 180° ( angle sum property means sum of all the the angles of the triangle is equal to 180 degree ) .

• x+x=180°-90°

• 2x= 90°

• x = 90°/2 = 45°

SO, VALUE OF X = 45° AND Y = 90°.

Full traingle value :- plus all angles inside traingle .

=> x+x+y = 45° + 45° + 90° = 180° .

HENCE PROVED.
