Answer:
Puedo responder a esto, pero ¿puedes acercar un poco?
Step-by-step explanation:
Firstly, we will draw diagram of this problem
we are given
∠DAB=125º
∠ACB=30º
Since, ∠DAB is exterior angle
∠ACB and ∠ABC are interior angles
and we know that
exterior angle is sum of two interior angles
so, we get
∠DAB=∠ACB +∠ABC
now, we can plug values
125º=30º+∠ABC
∠ABC=95º.............Answer
is the disk of radius 1 parallel to the
-plane and lying in the plane
. Parameterize this surface by

with
and
. Take the normal vector to
to be

(the orientation doesn't matter because this is a scalar surface integral)
Then


Answer:
2x+57°+x=180 ( angle sum property of triangle)
3x=123
x=41
