If line c is parallel to line d, the measure of angle 9 should be the same as angle 11 according to the Corresponding angles postulate. I<span>f a transversal (line b in this case) intersects two lines (lines c and d) and the corresponding angles are congruent, then the lines are parallel.
So now since the m</span>∠11 is 120 and m∠11 is congruent to m∠9 then we can solve for x.
m∠9 = 6x
m∠11 = 120
<span>
6x = 120
Divide both sides by 6 to get x.
6x/6 = 120/6
x = 20
The answer is then A. </span>
Answer:(3x+4)/x^2
Step-by-step explanation:
3/x+4/x^2
(3x +4) ➗ x^2=(3x+4)/x^2
if the perimeter of 1/4 of the circle is 7.14, then the full circle is 4(7.14) = 28.56.
and the radius is the same on any location of the circle.
Plane R and plane P intersect at AB.
Planes are when 3 points that are not on the same line can be used to describe a plane. Plane P is horizontal and Plane R is vertical and these 2 planes intersect at line AB. Intersecting is where these 2 planes meet, therefore line AB is common to both planes.
