finding the length of the missing side of the triangle?

Question

so if the sides of a triangle are 1.1 and the other one is 3.2 how would you find the awnser to how long the other side was???

Answer 1

*umm yeah. Sorry been out of high school too long haha.

Path. Theorum (spelling??) anyway... a2 + b2 = c2 (those are "squares" btw)

1.1 squared = 1.21
3.2 squared = 10.24
so you add those together and get 11.45
now take the square root of 11.45 and you have your answer.

Answer 2

If this is a right triangle and the missing side is the hypotenuse:
a2 + b2 = c2
So 1.1 multiply 1.1 = 1.21
3.2 multiply 3.2 = 10.24.
10.24 + 1.21 = 11.45
The square root of 11.45 is 3.38......~ 3.4
If it is not the hypotenuse, but another side, you have to use this:
c2-b2=a2
If it is not a right triangle: separate the triangle into two right triangles or one triangle one square etc. Use the theorem of Pittagora to find the side of the formed right triangle. You can see the other figure (square, rectangle etc.) to find the missing side,
Hope this helps.

Answer 3

You can use the Pythagorean Theorem. However, it only works for right triangles, true, but unless this is a right triangle, it will be impossible to determine the third side.

The other piece of information missing is whether or not 3.2 is the hypotenuse of the triangle or not.

If it IS the hypotenuse, then:

a^2 + b^2 = c^2
1.1^2 + b^2 = 3.2^2
1.21 + b^2 = 10.24
b^2 = 9.03
b = 3.00

If it ISN'T the hypotenuse, then

1.1^2 + 3.2^2 = c^2
1.21 + 10.24 = c^2
11.45 = c^2
c = 3.38

Good luck!

Answer 4

use the pythagorean theorem( where a squared plus b squared = c squared) the biggest side is c squared you add together the other sides squared to get c. Ex. 5 is your big side, 4 is your next down in line and the third and smallest side is missing, you find 5 times 5= 25 and 4 times 4= 16 you subtract 16 from 25 to get 9 which is three squared three is your missing side.

Answer 5

The Path Theorem only works for right Triangles.

Answer 6

Without knowing more information (like the measure of the angles of the triangle), it is impossible to determine the length of the third side.

Answer 7

using the pythagorean theorem a^2+b^2=c^2

1.1^2+3.2^2=c^2
1.21+10.24=c^2
11.45=c^2
sqrt of 11.45=c
3.3838=c

(1.1)^2+(3.2)^2=3.3838^2

Answer 8

i totally forgot, and im in college!

i think it has something to do with sin, cost, and tan when the triangle isnt right. if its right then its Asquared + Bsq. = Csq.

good luck
