Question

Use a system of equations to find x and y in each situation.

Answer 1

is that x and y?

Answer 2

yeah sorry hard to draw on here

Answer 3

we know that a triangle has 180 degrees enclosed within it, and also that since there is a 90 degrees in the triangle , you know the other angles must add up to 90

so for the 180 degrees

\[x+y+90=180\]
\[x+y=90\]

Answer 4

are you sure that's all that's given
