Answer:
108 deg
Step-by-step explanation:
Since sides DB and CD are congruent, then opposite angles are congruent.
m<C = m<B = 36
m<B + m<C + m<D = 180
36 + 36 + m<D = 180
m<D = 108

Answer: For a fence that has 18 posts he needs 36 rails.
Step-by-step explanation:
Hi, to answer this question we have to use proportions:
Each section use 3 vertical fence post and 6 horizontal rails
The proportion is = 3 post /6 rails
For 18 posts:
18 posts / x rails.
3 /6 = 18 /x
Solving for x:
x = 18 / (3/6)
x = 36 rails
For a fence that has 18 posts he needs 36 rails.
