a and b are the legs
we have
----> the height of the airplane
---> slant distance from the airport

First box is 100 second is 4 third is 1500 4th box is 60 and last box is 1560
Answer:
20:4
Step-by-step explanation:
got it for u
Lol its <span>0.00144300144</span>
if a b 9 are in GP
b÷a = 9 ÷ b
b^2 = 9a
if a - 1 b 9 are in AP
2b = a+8
b = a+8÷2
substitute
b is equal to a + 8 by 2 in b square equal to 9 a
(a+8÷2)^2 = 9a
a^2+16a+64 = 36a
a^2 -20a +64 =0
(a-16) (a-4) =0
a= 16 or a=4
when a=16 b= 12
when a=4 b= 6
Value of a and b are given above
