The two lines below intersect as shown what the value of x (2x+29) (9x-13)
tensa zangetsu [6.8K]

Given:

Two lines intersect each other.

Consider the below figure attached with this question.

To find:

The value of x.

Solution:

If two lines intersect each other then the vertically opposite angles are congruent and their measures are equal.

In the given figure, the measures of two vertically opposite angles are (2x+29)° and (9x-13)°.

2x+29=9x-13

2x-9x=-29-13

-7x=-42

Divide both sides by -7.

x=\dfrac{-42}{-7}

x=6

Therefore, the value of x is 6.

BARSIC [14]

slope = rise over run = y/x

A (-1,3) slope = 3/-1 = -3

B (1,2) slope = 2/1 = 2

C (-3,-1) slope = -1/-3 = 1/3

2 lines need to be negative reciprocals in order to be a right triangle

negative reciprocal of -3 is 1/3

 so this is a right triangle
