Given a right angle triangle with:

y = 8.00 m

r = 10.0 m

(a) We are to find the length of the unknown side x?

Using pythagoras theorem:

r² = x² + y²

x² = r² - y²

x = √r² - y²

Inputting values:

x = √10² - 8²

x = √100 - 64

x = √36

x = 6 m

Therefore, the length of the unknow side x is 10 m.

(b) The tangent of θ

Using SOHCAHTOA

Tan θ = Opposite/Adjacent

Opposite = y = 8 m

Adjacent = x = 6

Tan θ = 8/6

Tan θ = 1.3

(c) Sin σ

Sin σ = Opposite/Hypotenuse

Opposite = x = 6 m

Hypotenuse = r = 10

Sin σ = 6/10

Sin σ = 0.6
