If the angles are across from each other and the same degrees, they are vertical angles
if they add up to 90 degrees then they complementary angles
if they add up to 180 degrees they are supplementary angles
if the angles share a side, they are complimentary angles
To find the percent increase you need to first find how much the price went up: 2.65 - 2.4 = .25 Now divide .25 by the original price.
The formula for working out speed :
speed = distance ÷ time.
substitute the numbers : 100m ÷ 10.92s.
give your answer in meters per second ( m/s )
the answer I got while working this out was:
9.2 m/s.
The inscribed angle theorem says that

Triangle AOC is isosceles because both AO and CO are radii of the circle and have the same length. This means angles CAO and ACO have the same measure and are congruent.
Angles ACO and COD are congruent because they form an alternating interior pair between the parallel lines AC and OD.
Taking all these facts together, we have

and since angle COB is made up of angles COD and DOB, these angles must be congruent, and so the arcs they subtend (CD and DB, respectively) must also congruent.
