Answer:
19
Step-by-step explanation:
X will refer to the number.
X+57( the number added to the original.)=4x. (x time 4)
X+57=4x.
Subtract x from both sides to get the variable on one side.
(X+57)-x =(4x)-x
57=3x. You would then divide by 3 on both sides to again get integer isolated.
57/3=3/3x.
57/3=19. 3/3=1.
19=x.

<h3>
Pythagoras theorem</h3>
Pythagoras theorem is used to show the relationship between the sides of a right angled triangle. It is given by:
Hypotenuse side² = Adjacent side² + Opposite side²
Let x represent the distance from the satellite to the Earth's horizon
Hence:
- x² = 6370² + 600²
- x² = 40936900
- x = 6398 km
The distance from the satellite to the Earth's horizon is 6398 km
