Find A, B and C
Because the sides of the crosswalk are parallel and the sidewalks are also parallel, then the following relationships exist
---- alternate interior angles
---- alternate interior angles
To solve for B, we have:
--- the sum of the base angles
Recall that:
<span>An isosceles triangle has an order 2 rotational symmetry because it has 1 pair of congruent angles.
I hope this helpS!</span>
Plug them in:
x + 5y = 18
x - 3y = 10
F. (1,13)
G. (13,1)
H. (-2,4)
J. (-2,-4)
1 + 5*13 = 18 is obliviously not true so that takes out the first option.
13 + 5*1 = 18 : This is true but we have to check the next one.
13 - 3*1 = 10 : This is also true so we know this is the answer. We don't really need to check the other 2 but u can if u want to.
Hope that helped :) <span />
