Answer:

∠MLJ=180-90-51=39

∠LJK=180-90-72=18

\frac{14}{sin39} =\frac{LJ}{sin51} \\LJ=17.29\\\frac{KL}{sin18} =\frac{17.29}{sin90} \\KL=5.34

please feel free to ask if you don't understand any part of the above solution

Mrs. Kim is teaching a 5th grade class. She is standing 48 feet in front of Lester. Carey is sitting to Lester's right. If Carey
victus00 [196]

Lester and Carey are 14 feet apart

Step-by-step explanation:

Mrs. Kim is teaching a 5th grade class

  • She is standing 48 feet in front of Lester
  • Carey is sitting to Lester's right
  • Carey and Mrs. Kim are 50 feet apart

We need to find how far apart Lester and Carey

Look to the attached figure

The positions of Mrs. Kim, Lester, and Carey formed a right triangle

∵ The distance between Mrs. Kim and Carey is 50 feet

∴ The length of the hypotenuse of the Δ = 50 feet

∵ The distance between Mrs. Kim and Lester is 48 feet

∴ The length of one leg of the Δ = 48 feet

The formula of length of the sides of the right Δ is:

(hypotenuse)^{2}=(leg_{1})^{2}+(leg_{2})^{2}

Substitute the length of the hypotenuse and the length of the given leg in the formula above

∵ (50)² = (48)² + (leg)²

∴ 2500 = 2304 + (leg)²

- Subtract 2304 from both sides

∴ 196 = (leg)²

- Take square for both sides

∴ 14 = leg

∵ This leg represents the distance between Lester and Carey

∴ The distance between Lester and Carey = 14 feet

Lester and Carey are 14 feet apart

What is an equation of the line that passes through the point ( − 5 , − 1 ) (−5,−1) and is parallel to the line 4 x − 5 y = 10 4
Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

The equation of a straight line is expressed in the slope intercept form as

y = mx + c

Where m represents the slope

c represents the intercept.

The given equation is

4x−5y = 10

5y = 4x - 10

y = 4x/5 - 2

Comparing with the slope intercept form,

The slope,m = 4/5

The line that is parallel to the given line passes through the point (- 5,- 1)

If two lines are parallel, it means that they have the same slope. Therefore, the slope of the line that is parallel to the given line is 4/5

To determine the intercept c, we will substitute m = 4/5, x = - 1 and x = - 5 into the slope intercept equation. It becomes

- 5 = 4/5 × - 1 + c

- 5 = - 4/5 + c

c = - 5 + 4/5 = (- 25 + 4)/5 = - 21/5

The equation becomes

y = 4x/5 - 21/5
