Mouni  (8 years ago)

23.1 : 14.7= 11 : X
(i.e.,) 23.1/14.7 = 11/X
Now cross myltiply, (23.1) * X = 11* 14.7
(23.1) * X = 161.7
X = 161.7/23.1
X = 1617/231
X = 7

x=(11*14.7)/23.1
x=7

Is this solution Helpfull? Yes | No

tan x = 11 /23.1
tan x = a/14.7
equate above two equations :
i.e

11/23.1 = a/14.7
a = (11*14.7)/23.1 = 7m

Is this solution Helpfull? Yes | No
