Use this formula:
original amount - new amount
———————————————-
original amount
you just plug in the numbers in this formula now and solve
20-11 9
——— = —- = 0.45
20 20
multiply 0.45 by 100 to convert it into a percent
0.45 * 100 = 45
The answer is 45% !!
A rectangle is a shape that has 4 sides and 4 90 degree angles, a square however has 4 equal sides, and 4 90 degree angles
So Angle 5 = 1x - 7 and angle 2 = -2x + 18. You can work out that angle 1 is the same as angle 5 because corresponding angles are equal. Then you know that angle 1 + angle 2 = 180 because angles on a straight line add to 180. So therefore 1x - 7 -2x + 18 = 180 so -1x + 11 = 180 so -x = 169 so x = -169. Hope this helps :)
Answer:
Letter B
Step-by-step explanation:
Answer:
if they are congruent then the Parallel lines are cut
by a transversal
Step-by-step explanation:
The Alternate Interior Angles Theorem states that If two parallel straight lines are intersected by a third straight line (transversal), then the angles inside (between) the parallel lines, on opposite sides of the transversal are congruent (identical).
