Answer:

7

Step-by-step explanation:

(tangent)^{2} = AC × CB

 12^{2} = ( x + 9 ) 9

 144 = 9x + 81

 9x = 144 - 81

 9x = 63

 x = 63 ÷ 9

Solve 1/2x-4=7+1/6x​
Westkost [7]

Answer:

x=11/2

Step-by-step explanation:

1/2x-4=7+1/6x

1/2x-1/6x=7+4

6*1/2x-1/6*6=11      As 6 is the Lcm and we have to multiply it to the fractions.

3x-x=11                    As 6 divided by 2 is 3 and 3 multiplied by x is 3x.

2x=11

x=11/2 OR 5 1/2
