Answer:
y=1/2X+2
Step-by-step explanation:
The graph as a rise over run/slope of 1/2, therefore the beginning of the equation is 1/2, then you get the plus 2 from the fact that the graph starts at (0,2), not (0,0)
AA similarity
Using angle sum theorem, you can clearly find out the missing angles on the left and right triangles are 40° and 50° respectively.
Therefore, by using any two angles in the triangles, you can prove they are similar by AA similarity.
below
that is the procedure above
1 = 1.61
30 = x
1.61 x 30 =
48.3
the gcf of 16, 20, and 14 is 4
