Below is the solution>;

short side is 0.06m, and hyp is 1 m 
Sine is opposite/hyp 
sinθ = 0.06/1 
θ = 3.44º

Answer:

3.4°

Step-by-step explanation:

A 6.0 cm high elevation block is placed under one end of a 1.0 m long track.

Block is 6 cm high. It would stand vertically.

Stand one end of horizontal track 1 m long.

Please see the attachment for graph.

Let the elevation of block is Ф

In ΔABC, ∠B=90°

AB= 6 cm

BC = 1 m

First we change meter to centimeter. 1 m = 100 cm

So, BC = 100 cm

\(\tan\theta=\dfrac{AB}{BC}\)

\(\tan\theta=\dfrac{6}{100}\)

\(\theta=\tan^{-1}(0.06)\)

\(\theta\approx 3.4^\circ\)

Hence, The elevation of the track is 3.4°
