Answer:

u ≈ 5.7

Step-by-step explanation:

Using the Sine rule in Δ TUV, that is

\frac{t}{sinT} = \frac{u}{sinU} , substitute values

\frac{2.5}{sin26} = \frac{u}{sin85} ( cross- multiply )

u × sin26° = 2.5 × sin85° ( divide both sides by sin26° )

u = \frac{2.5sin85}{sin26} ≈ 5.7 ( to 1 dec. place )

Answer:option D is the correct answer

Step-by-step explanation:

The given triangle is a right angle triangle.

From the given right angle triangle,

The hypotenuse of the right angle triangle is 8

With m∠60 as the reference angle,

The adjacent side of the right angle triangle is 4

The opposite side of the right angle triangle is 4√3

To determine Cos 60, we would apply

the cosine trigonometric ratio.

Cos θ = adjacent side/hypotenuse. Therefore,

Cos 60 = 4/8 = 1/2

To determine Tan 60, we would apply the Tangent trigonometric ratio.

Tan θ = opposite side/adjacent side. Therefore,

Tan 60 = 4√3/4

Tan 60 = √3
