In the figure above, the two triangles are similar. You will need to find the value of x.  Make sure to provide proof that your solution is correct.  This should be written out and should be supported with an illustration(s) so we fully understand how you found your solution.  Once you have found your solution you will want to open paint and create the visual to support your explanation. 

Copy and paste your visual into the word document you used to write up your solution.  When you have completed the task and you are ready to submit your work you will need to open your own email and send your work to mathclasshonors@yahoo.com.  You can not just click on this link.  You will need to copy and paste this address in the "To" in your email.  You will attach your work in your email.  DO NOT cut and paste your work in the body of the email.

If you divide the given numbers by 8, they all equal 1.6, so if you multiply 6x1.6 that equals 9.6. The missing side is 9.6

12.8/8=1.6
8/5=1.6
12/5=1.6

So you divide the angle given for that bigger shape above because its 1.6 bigger, youll get the missing angle.

The missing side is 9.6 because if u divide 8 by 5 you will get 1.6 and if you divide 12.8 by 8 and you will get 1.6, And if u divide 9.6 by 6 you get 1.6, and 1.6 x 6 = 9.6.

The answer is 9.6 the i got it was like you got to flip the triangles to see who they diffrent so then you see how big it was so then you add it and i got this

We know that the x= 8.6
12.8+8+5+6+8=8.6 ish

when you divide 12.8 and 8 you get 1.6. when you do the same you to 5 and 8 you get 1.6

but for x i got 4 when divide 4 and 6 you get 1.5 that's as close as is can get

X=9 because you flip the triangle and can get the measure from the other triangle.

Divide 12.8 by 8=1.6
Divide 8 by 5 =1.6
Divide x by 6=?
Multiply 6 by 1.6=9.6
X=9.6

when i divided 12.8, 8 and then 5,8 i got 1.6 for everyone. but for x i divided the last number standing which is 6 and found out that 9.6 divided by 6 is 1.6

Well my guess for the shape problem is that X= 1.6. Well one of the reasons I thought the answer was 1.6 was because if you divide 12.8 with 8 the answer would be 1.6 I think all you need to do was divide to of the sides that all ready had the numbers on it and that’s my guess

I found that the value of “x” is equal to 9.6. To find this answer I used the sides on the bigger triangle and divided them by the same sides on the smaller triangle. The first side I divided 8 by 5 and got 1.6 and I checked the other side length and divided by its similar side and got the same answer of 1.6. So to find the value of “x” I found the x’s similar side and multiplied the side I knew by 1.6 and got 9.6.

The answer is 9.6, I got that answer by cross multiplying 8/5 and X/6 and that was 5x=48. Then divided 5 in both sides and it was 9.6.

X = 9.6

6 X
8 12.8


12.8 X 6= 76.8
76.8=8X
