4x + 3x = 98
7x = 98
x=14

4(14)=56 (one side of the monitor) - so this is a
3(14)=42 (other side of the monitor) - so this is b

diagonal, so use hypotenuse of two sides.

a squared + b squared equals c squared.

56 squared equals 3136
42 squared equals 1764
add those together and take the square root

the diagonal equals 70

Triangle G F E is cut by line segment H J. Line segment H J goes from side G E to F E. The length of G F is 4 x minus 4, the len
alexira [117]

Answer:

HJ = 8  JE = 4

Step-by-step explanation:

it is given that H is the midpoint of GE and J is the midpoint of FE. According to the midpoint theorem the line segment connecting the midpoint of two sides is parallel to the three side and its length is half of the third side. since JH is connecting the midpoints.

HJ= 1/2 (GF)

x + 3 = 1/2 (4x - 4)

x + 3 = 2x - 2

x = 5

^ Thus meaning the value of x is 5.

Now you just fill into your equations:

HJ = x + 3 = (5)  + 3 = 8

JE = x - 1 = (5) - 1 = 4

Therefore, HJ = 8; JE = 4.
