The answer is 172. hope that helps
the expression 
as a sum or difference is 
and , is simplified as 
.
<u>Step-by-step explanation:</u>
We need to rewrite the expression as a sum or difference , them simplify if possible , And the expression is :
From trigonometric identity we know that
Using the above identity we get:
⇒
⇒ 
⇒
⇒ 
⇒
Therefore , the expression as a sum or difference is and , is simplified as .
We can see the ratio of a side big figure and small figure is 60:15 or 60/15 = 1/4.
In decimal form we can write 1/4 as 0.25.
Therefore, scale factor is 0.25.
So, second option is applicable. Please check second option :
<h3>The scale factor is 0.25.</h3>
Now, let us find the side A by multiplying by scale factor 0.25 of the big figure.
The corresponding side of A is 35.
Therefore, A is 0.25 × 35 = 8.75 cm.
Therefore, other applicable option is 3rd option.
<h3>The length of side A is 8.75 cm.</h3>
