Answer:
The. angle is 72 and the supplement is 108
Step-by-step explanation:
Supplementary agnles are two angles with a sum of 180. So for example, two right angles would be supplementary.
Once again lets break this down by putting it into an equation. The supplement will be x. We know that 180 - x ( the supplement) will be equal to the angle but the angle is 2/3 the supplement.
Your equation should look like this x = 2/3 (180 - x).
Then we're going to multiply both sides by 3 to get 3x = 2 (180 - x)
You should distribute the 2 on the right side to then get 3x = 360 - 2x
You want to get x by itself but you can't make it just disappear because you need to keep your equation balanced. You're going to need to add 2x to both sides making your equation 5x = 360.
then you're going to divide 360 by 5 to get x = 72
subtract 72 (your angle) from 180 to get 108 which is your supplement.

Answer:
actually, a and b are correct, as any line is also parallel to itself (a).
b is probably the truly wanted answer, as this line is on a chart visible as a second line and parallel to the first one.
Step-by-step explanation:
the factor of x is also the slope of the line.
for a line to be parallel to another, both need to have the same slope.
the constant number in the equation is the offset of the line from point (0,0) in y direction.
so, b is a parallel line 4 units above the first line.
Answer:
x = 6.4 feet.
Step-by-step explanation:
If a triangle has side lengths a, b, and c then its perimeter (P) will be given by ( a + b + c ).
Now, in this problem, the perimeter of a triangle is given to be 27.1 feet,
And its sides are 9.8 feet, 10.9 feet, and x feet.
Therefore, 27.1 = ( 9.8 + 10.9 + x )
⇒ 27.1 = 20.7 + x
⇒ x = 6.4 feet (Answer)
