If
and
, separate variables in the differential equation to get

Integrate both sides:

Use the initial condition to solve for
:

Then the particular solution to the initial value problem is

(A)
You need to know the length of two sides and the degree of one angle.
(-7)*(2/5 + (-3/7))
= -14/5 + 3
=1/5
