Answer 1

y=-150 ' z = - 468

Explanation:

Sin angle = opp/hyp

Cos 30 = y/150

y = 150 ×( cos30)

y= - 150

Tan angles = opp / adj

Tan 60 = - 150 / Z

Z = (-150) / tan 60

Z = (-150) / 0.32

Z= - 468

Answer 2

y = 75

z = 43.3

Explanation:

To find the value of y we use the trigonometric identity Sine.

`sin\ 30 = (y)/(150)\\\\y=150*sin30\\y= 75\\`

Now to find the value of z we can use the trigonometric identity Tangent.

`tan\ 60=(y)/(z)\\\\z=(y)/(tan\ 60)`

We know the value of y is 75 so it becomes,

`z=(75)/(1.732) \\\\z=43.3`
