Determine the value of x for which rls if
A)10
B)0.75
C)1.25
D)20
Answer:
x = 1.25
Step-by-step explanation:
<1 and <2 are corresponding angles and if the lines are parallel, Â 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
Answer:
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:
[tex]\angle 1 =\angle 2[/tex]
Substitute the equations:
[tex]20-8x=30-16x[/tex]
Add 16x to both sides:
[tex]20+8x=30[/tex]
Subtract 20 from both sides:
[tex]8x=10[/tex]
Divide both sides by 8:
[tex]x=10/8=5/4=1.25[/tex]
So, our answer is C.
And we're done!
