Answer:
The answer is below
Step-by-step explanation:
A tangent is a line which touches a circle at one point. The angle between a tangent and a circle is 90°.
The two tangent theorem states that tangent that meet at the same point are equal in length.
Therefore:
CD = c + d
but c = 5.1, hence:
CD = 5.1 + d
12.1 = 5.1 + d
d = 7
AD = a + d; but AD = 12.2, d = 7
12.2 = a + 7
a = 5.2
AB = a + b; but b = 3.3
AB = 5.2 + 3.3 = 8.5
BC = b + c = 3.3 + 5.1 = 8.4
Perimeter of ABCD = AB + BC + CD + AD = 8.5 + 8.4 + 12.1 + 12.2 = 41.2
Answer:
Criag have left with 4 tickets .
Step-by-step explanation:
Criag have total no. of ride tickets = 232
Each ride of the Feris Wheel cost no. of tickets = 6
6 tickets are required to cover each ride of Feris wheel
So, 232 tickets are required to cover no. of rides of Feris wheel =
232 tickets are required to cover no. of rides of Feris wheel =
1 ride of Ferris wheel cost no.of tickets = 6
38 rides of Ferris wheel cost no.of tickets =
So, Tickets left = 232-228=4
Hence Criag have left with 4 tickets .
