Answer:
Step-by-step explanation:
we would like to solve the following using double-angle formula:
there're <u>4</u><u> </u>double Angle formulas of cos function which are given by:
since the question doesn't allude which one we need to utilize utilize so I would like to apply the second one, therefore
step-1: assign variables
to do so rewrite the given function:
so,
Step-2: substitute:
recall unit circle thus cos300 is ½:
simplify square:
reduce fraction:
simplify substraction and hence,

Answer:
B. AB/DE = AC/DF
Step-by-step explanation:
When triangles are similar, corresponding sides have the same ratio. We are told that ∆ABC ~ ∆DEF. This means that corresponding sides are ...
AB : DE
BC : EF
AC : DF
Any pair of these ratios can be used to write the proportion. Each proportion can be written in 4 different ways. The answer choices show that AB and DE are involved in the proportion we want, so we can have any of ...
AB/DE = BC/EF
AB/DE = AC/DF . . . . . . matches choice B
AB/AC = DE/DF
_____
<em>Additional comment</em>
When we say a proportion can be written 4 ways, we mean all of these versions of a proportion are fully equivalent:
- a/b = c/d
- a/c = b/d . . . . sideways
- b/a = d/c . . . . upside down
- c/a = d/b
