Answer:
AC = 18 ft
Explanation:
There is a geometric theorem that states that:
" In a triangle, the line joining two midpoints of two sides is parallel to the third side and equals have its length"
Now, let's check the given triangle:
M is the midpoint of AB
N is the midpoint of BC
Based on the above theorem:
MN will be parallel to AC
and
length of MN = (1/2) * length of AC
We are given that:
length of MN = 9 ft
Therefore:
9 = (1/2) * length of AC
length of AC = 2 * 9 = 18 ft
Hope this jhelps :)
Answer:
35
Step-by-step explanation:
When the two lines being crossed are Parallel Lines the Consecutive Interior Angles add up to 180°.
So, x + 12 + 4x - 7 = 180.
5x + 5 = 180
5x = 175
x = 35
