Determine the value of x for which rls if
A)10
B)0.75
C)1.25
D)20

x = 1.25

Step-by-step explanation:

<1 and <2 are corresponding angles and if the lines are parallel,  corresponding angles are equal

<1 = <2

20-8x = 30-16x

Add 16x to each side

20-8x+16x = 30-16x+16x

20 +8x = 30

Subtract 20 from each side

20+8x-20 = 30-20

8x= 10

Divide by 8

8x/8 = 10/8

x = 5/4

x = 1.25

C

Step-by-step explanation:

Since R and S are parallel lines, this means that Angle 1 and Angle 2 must be equivalent because they are corresponding angles. So:

Substitute the equations:

Add 16x to both sides:

Subtract 20 from both sides:

Divide both sides by 8:

So, our answer is C.

And we're done!

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
