All triangles have 180o in them when the 3 angles making them up are added together.
Givens
F = 90
E = 29
D = ???
Equation
<D + <E + <F = 180
Substitute and solve
<D + 90 + 29 = 180
<D + 119 = 180
<D = 180 - 119
<D = 61
I would say number 2 but dont take my word for it
Divide both sides by the numeric factor on the left side then solve x=9
Answer:
x=-7
Step-by-step explanation:
5x-2x+1=3x-6-x first combine like terms
3x+1=2x-6 combine like terms by subtracting 2x from both sides
x+1=-6 subtract 1 from both sides
x=-7
Answer:
y=3x-2 is a function because it passes the vertical line test.
