Two lines intersect at a point. the vertical angles formed are supplementary.

we know that

Vertical angles are a pair of opposite and congruent angles formed by intersecting lines.

so

Let

x1> angle vertical 1

x2> angle vertical 2

x1=x2 > equation 1

in this problem

if the vertical angles formed are supplementary

that means that

x1+x2=180 > equation 2

substitute equation 1 in equation 2

x1+x1=180

2x1=180

x1=180/2

x1=90 degrees

therefore

the answer is

The vertical angles are right angles

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

simplifying

7ln(x + 2.8) = 11.2

reorder the terms:

7ln(2.8 + x) = 11.2

(2.8 * 7ln + x * 7ln) = 11.2

(19.6ln + 7lnx) = 11.2

solving

19.6ln + 7lnx = 11.2

solving for variable 'l'.

move all terms containing l to the left, all other terms to the right.

reorder the terms:

-11.2 + 19.6ln + 7lnx = 11.2 + -11.2

combine like terms: 11.2 + -11.2 = 0.0

-11.2 + 19.6ln + 7lnx = 0.0

the solution to this equation could not be determined.

step-by-step explanation:

i searched it on google but it says that the solution to this equation could not be determined but i hope that it you a little.
