We can use the Pythagorean theorum

a^2+b^2=c^2

c^2 is the length of the longest side squared

so

6^2 + b^2 = 10^2

36+ b^2 = 100
-36 -36

b^2 = 64

b = 8

b is the same thing as your "x", so x = 8

Solve 7x - 2(x + 1) = 6x + 14 A) -12 B) 12 C) -16 D) 16

anzhelika [568]

7x - 2(x + 1) = 6x + 14
7x - 2x - 2 = 6x + 14
5x - 2 = 6x + 14
6x - 5x = -2 - 14
x = -16

answer
C) -16

Find the coordinates of the third vertex that completes the construction of a right triangle on the coordinate plane.

Neko [114]

Answer:

(7,a) Where a ∈ R - {7}

OR

(-2,a) where a ∈ R - {-2}

Step-by-step explanation:

The coordinates of the given line from the right to the left are:

(7,1) and (-2,1)

So, to make a right triangle, we need to make a right angle or by another words, we need to a make a perpendicular line to the given line (i.e: a vertical line parallel to the y-axis at one of the given points)

So, the third vertex must be on the line x=7 or x=-2

So, the coordinates of the third vertex is:

(7,a) Where a ∈ R - {7}

OR

(-2,a) where a ∈ R - {-2}
