Answer:
m<X =
Step-by-step explanation:
From the given isosceles triangle, we have;
<W and <V as the base angles
So that,
m<W = m<V = 27 (base angles of an isosceles triangle are equal)
Thus,
m<X + m<V + m<W = 180 (sum of angles in a triangle)
m<X + 27 + 27 = 180
m<X + 54 = 180
m<X = 180 - 54
= 126
m<X =
The integrals over B and T will be positive. Keeping fixed,
is strictly increasing over D as
increases, so the integrals over
(i.e. the bottom/top left quadrants of D) is negative but the integrals over
are *more* positive.
The integrals over R and L are zero. If we take , then
, which is to say
is symmetric across the
-axis. For the same reason, the integral over all of D is also zero.
