when running a line, in a right-triangle, from the 90° angle perpendicular to its opposite side, we will end up with three similar triangles, one Small, one Medium and a containing Large one.  Check the picture below.

\cfrac{4}{x}~~ = ~~\cfrac{x}{9}\implies 36=x^2\implies \sqrt{36}=x\implies 6=x

prohojiy [21]

update: 405.52 mg isn't the correct answer

Answer:

The answer to your question is  Equations 1, 2 and 5 are equivalent

Step-by-step explanation:

1.- Equation 1

    2 + x = 5              x = 5 - 2         x = 3

2.- Equation 2

    x + 1 = 4               x = 4 - 1         x = 3

3.- Equation 3

    9 + x = 6             x = 6 - 9         x = -3

4.- Equation 4

   x + (-4) = 7           x - 4 = 7          x = 7 + 4             x = 11

5.- Equation 5

   -5 + x = -2            x = 5 - 2         x = 3

zaharov [31]

Answer:

11° is the measure of the exterior angles

Step-by-step explanation:

Theorem:   Alternate exterior angles are congruent when two parallel lines cut by a transversal.

First we solve for x using the theorem

6x + 5 = 7x + 4

x = 1

Substitute x = 1 into 6x + 5

6(1) + 5 = 6 + 5 = 11°
