The sequence is arithmetic since the common difference that is equal
d=11-15=7-11=-4
a(n) = a1 +(n-1)d
a1=15
=
a(n) = 15+(n-1)-4
We know that
Applying the Pythagoras Theorem
c=²=a²+b²
where c is the diagonal of the wall
a=12 ft
b=6 ft
c²=12²+6²-----> c²=144+36-----< c²=180-----> c=√180------> c=6√5 ft
the answer is
<span>the exact length of the brace is 6</span>√5 ft

Hence, 
Answer:
C)The rays extend infinitely, and the angle is made by rays which have a common endpoint
Step-by-step explanation:
A ray is a line segment having one end point while extending in the other/opposite direction
An angle is made by two lines(rays) with common end point (vertex)
So when an angle is formed by the pair of intersecting rays the following options are ruled out
A) rays cannot have two end points
B) As rays extends infinitely in one direction, so having number of points is wrong
D)angles do not have lines
the following is best explanation is C
The rays extend infinitely, and the angle is made by rays which have a common endpoint !
