Question

find the value of the unknown angles in the following figure ​

Answer 1

The sum of all angles in a triangle is 180
So,
The diagnol makes two triangle as shown in that figure
So both triangle angle will be. 180
110+35+x=180
145+x=180
X=180-145
X=35
Now the value of y
45+40+y=180
85+y=180
Y=180-85
Y=95
