First we are going to set up two equations:
1)
2)
where x is the number of hotdogs sold, and y is the number of sodas sold. Let's subtract x from the second equation and set equal to 0:
1)
2)
Then let's add the two equations together to cancel out the y variable:
+
---------------------------------
Then solve for x:
So then return to equation 1 and plug in x to solve for y:
So then we know that x = 42 and y = 126; therefore, there were 42 hotdogs sold, and there were 126 sodas sold.
Answer:
Y = 10
Explanation:
We know that the left and top angles are 45°, the base is 10, and the bottom right angle is 90°, or a right angle. The simplest way I can explain this is the bottom side of the triangle is the same as the right side of the triangle. Meaning "y" would be 10 like the bottom.
If I'm right, I'd appreciate a brainliest as it'd really help me out :D

Answer:
Astronomers.
Step-by-step explanation:
In many, many ways we can use geometry in astronomy. One of the most or important example is that when astronomers find the distance between the different celestial bodies and they also find the tilt of any planet they uses geometry .
And in this field other uses of geometry when planets orbiting around the sun or satellites orbiting around there planets astronomers uses geometry to find the speed and velocity of the planets.
