Use the pythagorean theorem (a^2 + b^2 = c^2)


4^2 + 4^2 = c^2


16+ 16 = c^2


32 = c^2


sqrt(32) = c


The third option you have listed is the right answer (its 4sqrt(2) simplified)

Pythagoras Theorem:
 \boxed { \boxed {a^2 + b^2 = c^2 \beta }}

Apply Pythagoras Theorem:

a² + 6² = 11²

a² = 11² - 6²

a²= 85

a = √85

a = 9.22 (nearest hundredth)

Answer: RT = 9.22 cm

Jk =5x+17,KL = x -1,JL=7x-9 find a range of possible values for x
nadya68 [22]

Answer:

x = 25

Step-by-step explanation:

It is given that,

JK =5x+17,

KL = x -1,

JL=7x-9

We need to find the range of possible values for x.

It can be assumed that K is a mid point of JL.

JL = JK + KL

Putting all the values,

7x-9 = 5x+17 + x -1

Taking like terms together,

7x-5x-x = 17-1+9

x = 25

So, the value of x is 25.
