The value of the angle m∠4 is 105 degrees.

<h3>How to find angles in a quadrilateral?</h3>

The sum of angles in a quadrilateral is 360 degrees.

Therefore,

m∠1 + m∠2  + m∠3 + m∠4 = 360°

Hence,

x + x + 10 + x + 20 + x + 30 = 360

4x + 60 = 360

4x = 360 - 60

4x = 300

x = 360 / 4

x = 75

Therefore,

m∠4 = 75 + 30 = 105°

What value of r makes the equation true? r 0.12 = 0.20 A. r = 0.32 B. r = 0.08 C. r = –0.08 D. r = –0.32
muminat
Depends on your question...

If your question is r + 0.12 = 0.20 then do this:

Subtract 0.12 from both sides

r = 0.08

The answer is B.


If your question is r - 0.12 = 0.20 then do this:

Add 0.12 on both sides

r = 0.32

The answer is A

So it depends on your question :P

Ray knows that the m∠3 = m∠6. Which of the following conclusions can Ray make based on the given information? Lines l and m are
Slav-nsk [51]

If two lines are intersected by a transversal, and the alternate interior angles are equal, then the lines are parallel.

Conversely, if two lines are parallel, then the alternate interior angles formed by the transversal are equal.

So, Ray can made the conclusion that l and m are parallel because alternate interior angles are equal since m∠3 = m∠6.
