<span>Here's the rule.  I'm SURE you learned it in Middle School.  Or,
I guess I should say:  I'm SURE it was taught in Middle School.

                 Vertical angles are equal.

"Vertical angles" are the pair of angles that don't share a side,
formed by two intersecting lines.

AND ... even if you forgot it since hearing it in Middle School,
it was clearly explained in the answer to the question that
you posted 9 minutes before this one.


In #8, 'x' and 'z' are vertical angles.
         'y' and 116° are vertical angles.

In #9, 'B' and 131° are vertical angles.

In #10, 'B' and 135° are vertical angles.

For all of these, it'll also help you to remember that all the angles
on one side of any straight line add up to 180°. </span>

9. a. Maurice says that 1079 ÷ 62 is 16 with a remainder of 87. a. Without seeing his work, how can you tell Maurice divided inc
mamaluj [8]

Answer:

a.  We can tell that Maurice divided incorrectly because if the dividend is 62, you can't have a remainder of 87, because 62 goes into 87 once, so the answer would be 17 with a remainder of 25.  B. YOu can use that fact to find the correct quotient, because 87/62 is 1, with a remainder of 25, so 16+1=17, so the answer is 17 with a remainder of 25.   Please vote the brainliest.

Find the equation of the line that is perpendicular to the given line and passes through the given point.
Solnce55 [7]

Answer:

y = 3x + 2

y = 6x – 3

y = 2/3x + 6

y = –1/3x – 4

y = 2x + 1

Correct answer:

y = 3x + 2

Explanation:

Convert the equation to slope intercept form to get y = –1/3x + 2.  The old slope is –1/3 and the new slope is 3.  Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2

So y = 3x + 2
