Sine, cosine, and tangent to calculate the height of the buildings in the diagram below.

Around 68.0858 m

Step-by-step explanation:

To find x                            To find y  

To find the height of the building, add the x-value and y-value:

I hope this is correct o_o

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
