Answer:
the answer is triangles ABC and DEC are similar
Step-by-step explanation:
angle C is a common angle for both triangles
angle D is equal to angle A ( corresponding angles)since they are parallel
angle B is also equal to angle B for the same reason as angle D and A
since the three angles of the two angles are equal they are similar
((n-2)×180)/n = 156
(n-2)×180=156n
24n =360
n =15
360/n =36
n = 10
a)15 b)10
The answer is c because 8 - 5 is 3.
You'll be paying less for the tables because you're ordering fewer tables: 20 instead of 25.
Find the unit, after-tax price of a table:
$1,706.25
--------------- = $68.25 per table
25
Then, the total that must be paid to purchase 20 tables is
20($68.25/table) = $1,365
the answer is 3,5 because the estement of the ther is no negative
