B because first you do the two triangles which =3 then you get the area for the square in the middle which is 15 then you add them up to get 18
The answer would be 110 degrees.
So u just do 27*0.45 to get 12.15 and subtract that to get 14.85
Step-by-step explanation:
Soln,
Here,
45°+65°+y(let)=180°[ being a triangle]
or,110°+y=180°
or,y=180°-110°
so,y=70°
Now,
x=?
so,
x+y=180°[being straight angle]
or,x+70°=180°
or,x=180°-70°
x=110°
THEREFORE,x=110°
solved!
