Step-by-step explanation: Turn the mixed number into an improper fraction. -1 2/5 becomes -7/5. To divide fractions, you keep the first fraction, change the division sign to mulitplication and flip the second fraction. Then just multiply across the top and across the bottom. You will get 105/70. Reduce by dividing both numerator and denomination by 35 Result will be 3/2.

Hmm, Its pretty blurry and nice cat but I will try for ya :D ***cant gurantee its gonna be correct***

6 3/4 =27/4
2/3= 0.666666666 (0.66)
1 3/4= 7/4
2 1/4 = 9/4

(i can't solve this im so sorry holy shoot)

Given right triangle JKL, what is the value of cos(L)?

Daniel [21]

First option is correct.

Since we have given that

JKL is a right triangle.

Length of JK = 12

Length of KL = 5

By Pythagoras theorem, we get that

$JL^{2}=JK^{2}+ KL^{2}\\JL^{2}=12^{2}+ 5^{2} \\JL^{2}=144+25= 169\\JL=13$
