Y= 54 degrees


explaination: triangle angles = 180 degrees
So
180-72(the angle you already have)
108 then divide by 2 because that is how many more angles you have and you get 54.

Solve using any method. −2x+y=3 −3x+y=1 (-1, -2) (2, 7) (-2, -1) (-2, -5)
damaskus [11]

Answer:

Therefore the Final Solution is  x = 2 and y = 7  

i.e (2 ,7)

Step-by-step explanation:

Given:

-2x+y=3                ...............Equation ( 1 )

-3x+y=1                 ...............Equation ( 2 )

y=3x+1                   ..............Equation ( 3 )

To Find:

x = ?

y = ?

Solution:

Substituting Equation  ( 3 ) in Equation ( 1) we get

-2x+3x+1=3\\\\x=3-1\\\\\therefore x =2

Now Substituting x = 2 in Equation ( 3 ) we get

y=3\times 2+1=6+1\\\\\therefore y=7

Therefore the Final Solution is  x = 2 and y = 7  

i.e (2 ,7)
