From what i understand from the picture is there is a right angle triangle given with the hypotenes being 37, base being 12 and the perpendicular is 35.
we need to determine the value or Cos x
Easy way to remember which value to out where is
sinx=p/h -----> some people have
cosx=b/h ----> curly brown hair
tanx=p/b -----> through proper brushing
learned this is 8th grade in collage right now still comes in handy
we need cosx so we will use the second formula
![cosx=(b)/(h) \\\cosx=(12)/(37) \\x= cosx^(-1) ((12)/(37))\\](https://img.qammunity.org/2022/formulas/mathematics/college/701w1bgyuqse2a3we3250wbed39q11qezs.png)
which can then be simplified using a calculator
x= 71.1 degree
for this question from what i understand is the answer is cos x = cos (12/37)
