Answer:

√50

Step-by-step explanation:

tan X = opp/adj

tan X = 5/5

tan X = 1

X = tan-¹ 1

X = 45

but cos X = hyp/adj

X = 45

Cos 45 = C/5

1/√2 = C/5

5 = C√2

C = 5/√2

rationalize 5/√2 × √2/√2

5√2/2

so therefore, the answer is √50 bcos

√25×2

5√2

Please help. !!!!!!!!
Kryger [21]
Basically you find the data points and fill in the values. For Point J it is (2,4). They want you to do this: (2-4,4-6)...it then becomes (-2,-2).
So 
J: (-2,-2)
K: (-1, -4)
I: (-2, -5)
Those are your new points. I hope this helps love! :)
