Find the missing side lengths. Leave your answers as radicals in simplest form. 10 POINTS!!! ANSWER PLZ

D.

Step-by-step explanation:

Given

The triangle in the diagram above

Required

Find the missing lengths, u and v

To find the missing lengths, we have to check the relationship between the missing lengths, the given length and the given angle;

From trigonometry;

; Where Opp = Opposite and Hyp = Hypotenuse

From the attached diagram;

 becomes

Multiply both sides by

In radians,

Similarly, From trigonometry;

; Where Adj = Adjacent

From the attached diagram;

 becomes

Multiply both sides by

In radians,

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
