Answer:
Y=70
X= 20
You do first the adjacent angles 180-40 so 140 then u have that the triangle is isosceles so the bas angles are equal 180 -140 = 40
40 divided by 2 20 and 20 so x= 20
Then 90 -20 is 70
So 180 - (70+40)
180-110=70 so y= 70
Hope you understand

Answer:
The system has infinite solutions
Step-by-step explanation:
Notice that the 2nd eq can be written as y=3x+2, exactly the same first equation, so it doesnt give anything to solve it
You can see the attached picture represents the eq. 1
The second eq. is also represented in that picture, just it doenst seems, because it is hide under the first
