Answer:
x = 17
Step-by-step explanation:
Since the triangles are congruent
<I = <P
3x+4 = 72-x
Add x to each side
3x+4+x = 72-x+x
4x+4 = 72
Subtract 4 from each side
4x+4-4 = 72-4
4x = 68
Divide each side by 4
4x/4 = 68/4
x = 17
Answer:
25 train routes
Step-by-step explanation:
The train routes go from 1-2, 2-3, 3-4, 4-5, ,and so on, but there is also one that goes from 25-1. If you notice, there when we get to 4-5, there are 4 train routes which means that if there are 25 towns, then there are 24 train routes, but since 25 and 1 are connected then there are 25 routes. Hope this helps!
It would be 47°. you would add 45 and 88, getting 133. then take 180 (all triangles,usually, equal 180°) and subtract 133. getting your answer, 47° as the missing angle. hope this helped!!

Answer:
The four pieces cut off can be arranged into two squares with sides of length b feet and hence the area of the octagon is w 2 - 2 b 2 square feet. Since w = 12 feet, all that is needed is to find b. square feet which is approximately 119 square feet.
