Answer:

x=27

∠JLK=2x+1=2(27)+1=55

Step-by-step explanation:

∠A+∠K=180

3x+13+∠K=180

∠K=167-3x

∠K+∠L+∠J=180

167-3x+39+2x+1=180

207-x=180

x=27

∠JLK=2x+1=2(27)+1=55

Don't worry, you aren't gonna fail. Take a deep breath and relax. Geometry is tricky but you got this. Have a nice night.

Answer:

x = 27°
∠JLK = 55°

Step-by-step explanation:

∠AKL is exterior angle and as per property it is equal to sum of two non-adjacent angles:

∠AKL = ∠ KJL + ∠JLK

3x + 13° = 39° + 2x + 1°

Solving for x

3x - 2x = 39° + 1 - 13
x = 27°

And finding the value of ∠JLK:

∠JLK = 2x + 1 = 2*27° + 1° = 55°

Ruby is taking a road trip to see her parents. She drives 114 hours which covers 18 of her trip. How many hours will it take her

slega [8]

Answer: It will take 10 hours.

Step-by-step explanation:

Given: Distance traveled by Ruby in $1\dfrac14$ hours = $\dfrac{1}{8}$ of Total trip.

i.e. Time taken to complete $\dfrac{1}{8}$ of Total trip= $1\dfrac14$ hours

Time taken to cover the total trip = Reciprocal of $\dfrac{1}{8}$ x ( $1\dfrac14$ )

$=\dfrac81\times(\dfrac{5}{4})\\\\=2\times5\\\\=10\text{ hours}$

Therefore , it will take 10 hours to complete the trip.
