True.

Step-by-step explanation:

Linear measurement : It is defined as the measurement of length.It also measure thickness, height and diameter. It is can be measured in meter, inches, centimeter, feet etc.

We are given that

$tan 34'15''=\frac{x}{12}$

$tan\theta=\frac{perpendicular}{base}$

Therefore, height of triangle =x, base of triangle= 12 units

We change 15 seconds into minutes

1 minute =60 seconds

$\therefore 15 seconds=\frac{15}{60}=\frac{1}{4} minutes$

Now add 34' to $\frac{1}{4}$ minutes then we get

$34+\frac{1}{4}=\frac{136+1}{4}=\frac{137}{4} minutes$

Now , we changing minutes into degree

1 degree= 60 minutes

Therefore , $\frac{137}{4} minutes = \frac{137}{240}=0.5708 degrees$

$tan(0.5708^{\circ})=\frac{x}{12}$

$0.00996=\frac{x}{12}$

$x=12\times 0.00996=0.11952=0.1195$

By cross multiply

x=0.1195 units

Height =x=0.1195 units

It is linear measurement.

Therefore, it is true.
