Hyperloop, a new mode of travel, aims to reach a speed of 170 m/s . This is 50% less than the speed of sound.

mariarad [96]

Answer:

The speed of sound is $340\ m/s$

Step-by-step explanation:

Let

x-----> the speed of sound

we know that

$50\%=50/100=0.50$

$0.50x=170$

solve for x

$x=170/0.50=340\ m/s$

Bethany used the steps below in an attempt to solve for angle B in triangle ABC.

Sonja [21]

Given that,

The area parameters are

A = 2.7 cm, B = 4.1 cm C = 4.5 cm

We want to find the angle extended by B.

Using cosine Rule

b² = a² + c² - 2ac•Cosθ

4.1² = 2.7² + 4.5² - 2 × 2.7 × 4.5• Cosθ

16.81 = 7.29 + 20.25 - 24.3•Cosθ

16.81 - 7.29 - 20.25 = -24.3•Cosθ

-10.73 = -24.3•Cosθ

Cosθ = -10.73 / -24.3

Cosθ = 0.4416

θ = Cos~1 (0.4416)

θ = 63.8°

The angle B is 63.8°
