If you plug the values for a, b, and c into the Pythagorean Theorem, you can get x alone to figure out the side lengths:
x² + 3x² - 1² = 3x² + 1²
Combine like terms
4x² - 1² = 3x² + 1²
Subtract 3x² from both sides
x² - 1² = 1²
Simplify 1²
x² - 1 = 1
Add 1 to both sides
x² = 2
Square root both sides
x = 1.41421
Then, simply plug in that number for x on each side! It comes out to a weird number, but I don't see any other way to solve it...
Hope this helps :)
Answer:
To find average speed, you divide total distance by total time.
Answer:
P=40
Step-by-step explanation:
find the distance between each vertices:
between the following points to find the length of each sides, octagon has 8 sides , since it is regular pentagon the distance between each vertices =5
the length of each side of octagon=5
to check :d=√(x2-x1)²+(y2-y1)²
(-2,-4) and (1,0) , d=√[(1-(-2)]²+(0+4)² =√3²+4², d=5
(1,0) and (1,5) , d= 5
(1,5) and (-2,9) , d=5
(-2,9) and (-7,9) , d=5
(-7,9) and (-10,5) , d=5
(-10,5) and(-10,0) , d=5
(-10,0) and(-7,-4), d= 5
(-7,-4) and (-2,-4), d=5
perimeter of octagon = 8a ( a is the length of the side)
p=8(5)
P=40
A teacher's perspective...I really want to believe the intent of this site was a good one. Getting help with homework is a good idea. But brainly has become a cheat site for many students. I catch so many who admit later that they searched the question, found the answer, copied & pasted, and never try to understand the problem or its answer. I warn them that the answers from brainly are often wrong, or have strange approaches. (Like using calculus to find the vertex in Algebra, for example.) And I've heard from school administrators that brainly won't remove their curriculum test and quiz answers from the site. The sad part is that this sets up students to struggle more moving forward, and doesn't help in the long run. How do I know? I tutor kids who cheat their way through online courses and then freak out when they have to prepare for SATs or placement tests. This site was already moving in this direction when it was Open Study, but has gotten even worse with the pay wall and premium accounts. It upsets me that a site alleging to be educational is profiting from cheating and hurting students in the long run.
