Answer: The sum of the measures of the angle inside of a triangle add up to 180 degrees. That's all we're doing over here. And so let's see if we can simplify this a little bit. So these two guys-- 90 plus 90's going to be 180, so you get 180 minus theta …

Answer:
<em>We can't find a unique price for an apple and an orange.</em>
Step-by-step explanation:
Suppose, the price of an apple is
and the price of an orange is ![y](https://tex.z-dn.net/?f=y)
They need $10 for 4 apples and 4 oranges. So, the first equation will be.......
![4x+4y=10 ........................................(1)](https://tex.z-dn.net/?f=4x%2B4y%3D10%20........................................%281%29)
They also need $15 for 6 apples and 6 oranges. So, the second equation will be........
![6x+6y= 15 ........................................(2)](https://tex.z-dn.net/?f=6x%2B6y%3D%2015%20........................................%282%29)
Dividing equation (1) by 2 on both sides : ![2x+2y= 5](https://tex.z-dn.net/?f=2x%2B2y%3D%205)
Dividing equation (2) by 3 on both sides : ![2x+2y=5](https://tex.z-dn.net/?f=2x%2B2y%3D5)
So, we can see that both equation (1) and (2) are actually same. That means, we will not get any unique solution for
and
here. Both
and
have <u>"infinitely many solutions"</u>.
Thus, we can't find a unique price for an apple and an orange.
