 The formula to find a hypotenuse is as follows:
a^2 + b^2 = c^2
Write out your triangle, labeling one part as 18, and another as 80. Connect a line between the end points of each line, and give a letter to a value. For my example, I will use 18 as a and 80 as b. 
18^2 + 80^2 = c^2
Solve this by squaring these numbers.
324 + 6400 = c^2
Add these numbers
6724 = c^2
 Then, finally, deprive the square root from 6724 and c^2
82 = c
 Since c is you hypotenuse, 82 centimeters is your answer. This checks out because your hypotenuse must be the largest number of the three, and if not, you did something wrong. However, this all checks out, meaning your hypotenuse is 82 centimeters. Hope this helped!

a^2 + b^2 = c^2\\\\18^2 + 80^2 = c^2\\\\6724 = c^2\\\\c = \sqrt{6724}\\\\ c = 82

The hypotenuse is 82 centimeters long.

Angle K = angle M

(4x-1)=(2x+27)

4x-2x=27+1

2x=28

x=14

K=4x-1 then 4(14)-1
55 degrees
M=2x+27 then 2(14) +27
55 degrees
K+M+L =180
55+55+L=180
110+L=180
L=70 degrees
Therefore K=55 degrees M=55 degrees L=70 degrees

What is the answer for this
Eva8 [605]
1). 2x-1=5 (cause x can really be anything) solve the equation to get x=3 or in this case, triangle = 3.

2). Using the info from above, we get the equation 3+x=1.
Solving this equation we get, x (square) =-2.

3). Using all the info from the above problems we get the equation: 3-2*-2=x
Solving that we see that x (star) equals 7.

In conclusion:

Triangle=3
Square=-2
Star=7
