Question

Find the unknown side: V u 2.5 85 26

Answer 1

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 )
