Answer:

33 meters

Step-by-step explanation:

According to the Pythagorean theorem :

65²=56²+x² (the hypotenuse is 65 meters)

x²=65²-56²=4225-3136

x²=1089

x= $\sqrt{1089}$

x=33 meters

Find the missing side length

Alex777 [14]

Answer:

The missing side length is 36

Step-by-step explanation:

You need to find the ratio of the dilation so if you take corresponding sides, for example, 72 and divide by 8 you get 9. So, if you multiply each side of the triangle XYZ by 9, it should get the length of the sides on triangle ABC.

4 * 9 = 36

Hope this helps! :)

$-4(4x+4)=2(2-7x) \\

-2x=20\\
x=-10\\\\
-4(4\cdot(-10)+4)=2(2-7\cdot(-10))\\
-4(-40+4)=2(2+70)\\
-4\cdot(-36)=4+140\\

Explain the error in the student’s work 3(x − 5) = 273(x − 5) + 5 = 27 + 53x = 333x3 = 333x = 11

astra-53 [7]

3(X-5)=27. 3x-15=27. 3x=42. X=14. It looks like they tried to add 5 instead of multiplying it, and they added 5 and 27 wrong. :)
