Find the length of AC

Step-by-step explanation:

To find the length of AC we use cosine

cos∅ = adjacent / hypotenuse

From the question

AC is the adjacent

AB is the hypotenuse

AB = 58

cos 51° = AC / AB

cos 51 = AC / 58

AC = 58 cos 51

Hope this helps you

Option A is the correct option

Step-by-step explanation:

In ∆ABC , <A = 51°

For <A = AC = adjacent = X

AB = hypotenuse = 58

Now,

Hope this helps...

Good luck on your assignment...

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
