In ΔJKL, j = 74 cm, k = 14 cm and l=80 cm. Find the measure of ∠J to the nearest degree.
natita [175]

Answer:

  ∠J = 60°

Step-by-step explanation:

The Law of Cosines tells you ...

  j² = k² +l² -2kl·cos(J)

Solving for J gives ...

  J = arccos((k² +l² -j²)/(2kl))

  J = arccos((14² +80² -74²)/(2·14·80)) = arccos(1120/2240) = arccos(1/2)

  J = 60°

Who do I do this problem
Leviafan [203]
You subtract 16 from each side of the equation.
Then it will say exactly what number 'n' is.
_______________________________________

The equation is                    n + 16 = 9

On the left side, you subtract 16 from (n + 16) and you have 'n'.

On the right side, you subtract 16 from 9 and you have  -7 .

Now the equation says          n      =  -7

Nancy had 16 chocolate candies in a bag. Her mother put a handful of candies in the bag. When Nancy counts her chocolate candies
Reika [66]

Answer:

she had 16

16

She got c

16 + c

She now has 32

16 + c = 32

I don't know if that's the exact answer, but basically, 16 needs to be added to c, and it needs to equal 32.  

Hope this helps! :)
