Find the exact value of x

Step-by-step explanation:

idk what grade you're in but I solved it using a system of equations. there could be an easier method but this is what I did:

1. label each of the sides x, y, z

2. SINCE they're all right angle triangles we can use Pythagorean theorem to create the base generation equation

3. rewrite whole formula in terms of x with y in its components

4. using the mini triangle x can also be rewritten with z in its components

5. equate them together to isolate for a variable, z

6. solve for y by rewriting a formula using the other mini triangle

7. now plug on the equation u isolated with z to get y value

8. plug y back into the formula you wrote in terms of x

to check:

6^2 + 6.71^2

= 81 which equals the hypotenuse of the while triangle

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.

the square root of 16 is 4.

4*4 = 16
