Cos problems

Question

Triangle LIT is similar to triangle YOU. LI=14 in, IT=48 in, LT=50 in and angle I=90 degrees . What is cos (u)

Answer 1

triangle LIT is similar to triangle YOU

I assume angle u is angle YUO

angle u has the same measure as angle LTI because the triangles are similar

cos=adj/hyp

cos=48/50

cos(u)=96/100=0.96

using arcos...

angle u has degree measure of 16.260204710º or 16º 15' 36.737"
