What other information do you need to prove triangle INF=CAT by the ASA Postulate?
1 answer:
Label the angles on the given figure an x and y and label the unknown angles as z (see the figure below).
Because the sum of angles in a triangle = 180°, angle z is correct for all three triangles.
In order to prove that ΔINF = ΔCAT by the ASA Postulate,
1. We should show that AC = IN, or
2. We should show that AT = NF.
Proving either of the two options means that we have congruent isosceles triangles.

Answer:
Price of 1 child ticket is $5.4
Price of 1 adult ticket is $10.8
Step-by-step explanation:
Given:-
6 children and 2 adults are going for circus.
Children ticket is half the price of adult ticket.
Total ticketing cost =$54
To find:-
Cost of 1 child ticket=?
Cost of 1 Adult ticket=?
Solution:-
Let price of 1 child ticket be x and price of 1 adult ticket be y,
therefore from the given data we get 2 equations,
-----------------------------------(1)
--------------------------------(2)
Now, substituting the value of x from equation 2 in equation 1,
------------------------(3)
Now, substituting the value of y from equation 3 in equation 2,
------------(from equation 3)
----------------------(4)
As, x is price of 1 child ticket and y is price of 1 adult ticket,
Therefore price of 1 child ticket is $5.4 and price of 1 adult ticket is $10.8
