Answer: this theorem is true.

Step-by-step explanation: this theorem is in fact true. perpendicular lines mean one line cuts through another line and forms 90 degree angles. if two lines were to cut through the same line, then both lines would have to be parallel to each other considering the definition of perpendicular lines. for example in the picture both lines are completely horizontal making them form 90 degree angles. if these lines did not form 90 degree angles then they would not be perpendicular and at some point would cross paths. however they are straight meaning they will never touch, hence the parallel line definition.

Answer:

Check it out the paragraph below

Step-by-step explanation:

1) 1st Statement: 1) \:Given: r\perp\: s,\: t\perp s\\ Reason: Given 2) 2nd Statement: \angle 4 \:and\: \angle 8\:are\:right\:angles Reason: Lines are perpendicular when form right angles by meeting another line. 3) 3rd Statement: \measuredangle 4 =90^{\circ}\:and\:\measuredangle 8=90^{\circ} Reason: Definition of Right Angles. 4) 4th Statement: \measuredangle 4\cong \measuredangle 8 Reason: Congruent angles have the same angle measure. 5) 5th Statement: r\parallel s Reason: If their corresponding angles are congruent, then their lines are parallel. (Corresponding Angles Theorem).

I don’t get this :(
muminat
Ok so for the first one it’s super simple I’m gonna do it as less complicated so it can help you :)


So first we need to convert the mixed number to an improper fraction


1 4/5 = 9/5


Now we need to reduce the numbers greatest common divisor which is 3

3/5 x 6

Now multiply the numbers


Your answer is 18/5 I hoped this help



Now for the second one

this one is a little more complicated and I don’t know how to make it sound easier so I’m gonna tell you the answer which is 580/21


The last one is the same steps we did for the first one which is 27/20



I hoped this helped you it is a little difficult but you’ll get the hang of it :)
