Question

find the value of y from figure?
...plzz answer quickly.

Answer 1

Dear friend,

From the above figure ,

We have a 90° angle in which it contains more two angles

2y and y

So,
2y + y = 90°
3y = 90°
y = 90/3
y = 30°

2y = 2 × 30 = 60°
y = 30°

Answer. 2y is 60° and y is 30°.

Hope it helps !!!

Answer 2

Angle AOC=90degree
Therefore,
Angle AOD+Angle DOC=90degree
2y + y =90degree
3y=90degree
y=90/3 degree
Therefore,y=30degree
