Answer:

120

Step-by-step explanation:

75 + 45 = 120

The triangle adds up to 180.

180 - 120 = 60

Therefore the inside of the triangle is 75, 45, and now 60 which all adds up to 180.

Now to find Angle 1.

180 - 60 = 120

With Angle 1 being 120

Debora [2.8K]

Answer:

x=-1, y=5. (-1, 5). The first number is -1 and the second number is 5.

Step-by-step explanation:

6x+2y=4

2x+4y=18

-12x-4y=-8

2x+4y=18

----------------

-10x=10

x=10/-10

x=-1

6(-1)+2y=4

-6+2y=4

2y=4-(-6)

2y=4+6

2y=10

y=10/2

y=5
