In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.

wariber [46]

Answer:

∠W = 16.3°

Step-by-step explanation:

In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.

From that above question, we are given 3 sides and we are to find the angle of one of the sides.

We solve using Cosine rule.

∠W = arc cos (v² + x²﹣w²/2vx)

∠W = arc cos (64² + 63² - 18² /2 × 64 × 63)

∠W = arc cos (0.9599454365)

∠W = 16.27137°

∠W = 16.3°

Answer:

$54$

Step-by-step explanation:

$a_1 {r}^{n - 1} \\ 2 \times {3}^{4 - 1} \\ 2 \times {3}^{3} \\ 2 \times 3 \times 3 \times 3 \\ 2 \times 9 \times 3 \\ 18 \times 3 \\ = 54$
