Find the following ratios. Write each answer as a fraction and as a decimal rounded to four decimal places.

Alona [7]

Answer:

$y = 56.6208$

Step-by-step 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:

$cos(39) = \frac{44}{y}$

i.e.

$cos(\theta) = \frac{Adjacent}{Hypotenuse}$

Make y the subject

$y = \frac{44}{cos(39)}$

$y = \frac{44}{0.7771}$

$y = 56.6208$ -- approximated
