J stands for Jon, A stands for Angelica, and C stands for Chaya.

J = C - 3
A = C + 4
C = A - 4

= 196 h

62 + 65 + 69 = 196

Jon worked 62 hours, Chaya worked 65 hours, and Angelica worked 69 hours.

And that's your answer! ^ I hope this helped you! c:

Length of KL is 17 units

Given that;

L is mid point of KM

KL = 2x - 3

LM = x + 7

Find:

Length of KL

Computation:

We know that,

L is mid point of KM

So,

KL = LM

2x - 3 = x + 7

2x - x = 7 + 3

x = 10

So,

Length of KL = 2x - 3

Length of KL = 2(10) - 3

Length of KL = 20 - 3

Length of KL = 17 units

Identify the angle relationship, write an equation and Solve for x.

irakobra [83]

Answer:

$2x-6+x+x=180$

$4x-6=180$

$4x=180+6$

$4x=186$

$x=\frac{186}{4}=46,5°$

Step-by-step explanation: the other angle is equal to his simmetrical, cause the triangle is isosceles, so is value is x. The sum of the angle in a triangle must be 180°
