Answer:
Step-by-step explanation:
Since two sides of the triangle are equal in length, we can conclude that 
is an isosceles triangle. With this information, we can draw an isosceles triangle to find 
. Since the base angles of an isosceles triangle are equal, we can solve for :
(Angle sum of triangle is 
)
(Base angles of isosceles triangles are equal, there is an image attached to show that is one of the base angles)
Hope this helps :)
We are given with the rate of change of the base, db/dt equal to 1 ft/ sec and the rate of change of the height of the triangle, dh/dt equal to 2 ft/sec. b is 10 ft and h is 70 ft. Area of triangle is equal to A= 0.5 bh The rate of change of the area is equal to dA/dt = 0.5 b dh/dt + 0.5 h db/dt. Substituting, dA= 0.5*10*2 + 0.5*70 * 1 equal to 45 ft2 / sec.
