Answer :

Certainly! Let's solve the given problem step by step.

The information provided seems to be:

1. An angle of 66°
2. An expression: (78 - 4)

To find the value of [tex]\( s \)[/tex]:

Firstly, let's simplify the expression given in the parentheses:

[tex]\[ 78 - 4 = 74 \][/tex]

Now, we combine this with the angle measurement provided (66°). However, the context is not entirely clear. We'll consider a possible scenario where we are looking for an expression involving an angle and a simplified number:

Possible Interpretation:

Since no specific relationship between the angle and simplified value is specified, we might assume the problem wants to identify a right triangle using these values, or there's some context missing. For now, let's consider the possibility it's a geometric or trigonometric expression.

One could be asked to sum these numbers or treat them as parts of trigonometric identities:

For simple addition (which is one of the potential simplest interpretations):

[tex]\[ 66 + 74 = 140 \][/tex]

Thus:

[tex]\[ s = 140 \][/tex]

If there is a possibility we consider these as separate values for different contexts such as sin or cos:

Let's first assume these measurements simply need combination by summation:

[tex]\[ s = 66 + 74 = 140 \][/tex]

That could be the most straightforward interpretation without further context.

If you need more specific geometric or trigonometric relationships, please provide additional context!

So the final solution with basic arithmetic:
[tex]\[ s = 140 \][/tex]
