Answer: ![x=58+57=115](https://tex.z-dn.net/?f=x%3D58%2B57%3D115)
![y=178-115=63](https://tex.z-dn.net/?f=y%3D178-115%3D63)
Step-by-step explanation:
Let x be the number of computers Grade 3 and grade 4 has and y be the numbers of computers the rest of school has.
Then, x= Grade 3 computers +Grade 4 computers.
![\Rightarrow\ x=58+57=115](https://tex.z-dn.net/?f=%5CRightarrow%5C%20x%3D58%2B57%3D115)
And y = Total computers - x
![\Rightarrow\ y=178-115=63](https://tex.z-dn.net/?f=%5CRightarrow%5C%20y%3D178-115%3D63)
Therefore, The equations can be used to find how many computers the rest of the school has.
![x=58+57=115](https://tex.z-dn.net/?f=x%3D58%2B57%3D115)
![y=178-115=63](https://tex.z-dn.net/?f=y%3D178-115%3D63)
X = 8 since the two triangles are congruent, measure of angle J is the same of the measure of angle T ..therefore you can set up: 97+37+4x+14 = 180..(total degrees in a triangle). now solve for x
