Question

In ΔUVW, w = 9.7 cm, ∠W=110° and ∠U=42°. Find the length of u, to the nearest 10th of a centimeter

Answer 1

6.9

Explanation:

Answer 2

9514 1404 393

Answer:

6.9 cm

Explanation:

The law of sines is useful here:

u/sin(U) = w/sin(W)

u = w · sin(U)/sin(W) = (9.7 cm)sin(42°)/sin(110°)

u ≈ 6.9 cm
