Answer:

y = 56.6208

Explanation:

Given

The attached triangle

Required

Find y

To find y, we make use of the relationship between sides lengths 44 & y and angle 39

The relationship is:

cos(39) = (44)/(y)

i.e.

$cos(\theta) = (Adjacent)/(Hypotenuse)$

Make y the subject

y = (44)/(cos(39))

y = (44)/(0.7771)

y = 56.6208 -- approximated
