Find the value of x. Please help!!!!
Murrr4er [49]

Answer:

9°

Step-by-step explanation:

In a ∆, equal sides make equal angle to the third side. So the angle that's not mentioned is same '2'.

Sum of angles in a ∆ = 180°

80° + m/_2 + m/_2 = 180°

80° + (5x + 5) + (5x + 5) = 180°

10x + 90° = 180°

10x = 90°

x = 9°

Jill and Lori each walk in a straight line between two points. Using the points on a map they created, Jill will start at (–2,–4
Olenka [21]
We develop the equation for each of the tracks that will be walked through by Jill and Lori. 
                   Jill:  y - 2 = ((2 - -4)/(4 - -2))(x - 4) ;   y = x - 2
                   Lori: y - 6 = ((-4 - 6)/(4 - -1))(x + 1);   y = -2x + 4
The intersection of these equation is (2,0).
