Need help with this please ​

These are kinda tuff  Mandi,  sooo remember what's below

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

now fine one of the above functions that has the 3 things you are working with.   2 knowns, and 1 unknown

also we know that the angle at the right tip of the triangle is 90-59= 31°

we know that b/c the inside angles of a triangle always add to 180 and there is already a 90° so we only have 80 left, which the 59° is part of, so 31 is the other, now put that info into one of the above formulas

x= adjacent side

and we know the angle and hypotenuse side.    find the formula with those parts.  I see Cos  has those or CAH... to help remember how those fit

Cos(31) = x / 17

17*cos(31) = x

14.5718 = x

there is your answer,  understand how I got it? :)

just needed some points but try socratic

the equivalent expression are always the hardest ones but you look at the gcf also
