Answer:

Step-by-step explanation:
Given
The above diagram


Required
Determine length AB
Tangents drawn from the same point of a circle are equal;
<em>This implies that</em>

Substitute values for AB and AC

Subtract 3y from both sides


Divide both sides by 8



Substitute
for y in 




Step-by-step explanation:
x = ky, where k is a real constant.
When y = 36, x = 24.
=> (24) = k(36), k = 2/3.
Hence x = (2/3)y.
When y = 132, x = (2/3)(132) = 88.
Answer:
57,600
Step-by-step explanation:
720 * 80 = 57,600
Answer:1375
Step-by-step explanation:
X= 15 is given
X squared is 15x15 = 225
1600 - 225= 1375
You can divide 1000 by 4 then multiply a number to get 2500
1000/4= 250
250 x 10 = 2500
