Answer:

Answer 1

`x = 13.8`

Explanation:

Given

See attachment for triangle

Required

Find x

To find y, we make use of the relationship between sides lengths 11 & x and angle 37

The relationship is:

`cos(37) = (11)/(x)`

i.e.

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

Make x the subject

`x = (11)/(cos(37))`

`x = (11)/(0.7986)`

`x = 13.7741`

`x = 13.8` -- approximated
