Answer:

<h2>The hurricane's speed was 200kmph</h2>

at average

Step-by-step explanation:

The way how we can find this is <em>simple</em>. If we look at the graph, we see that in 1 hour, the hurricane traveled at a constant rate of 200kmph

Hence, the hurricane's average speed was 200kmph

Triangle A B C is shown. Angle A C B is a right angle. The length of the hypotenuse is 20.

Answer:

The length of BC is needed because it is the side opposite ∠A.

Step-by-step explanation:

Given the right angles triangle as shown in the attachment, we can get sin(A) without using Pythagoras theorem. Instead we will use SOH CAH TOA trigonometry identity.

According to SOH:

Sin(A) = Opposite/Hypotenuse

Sin(A) = |BC|/|AB|

Opposite side of the triangle is the side facing ∠A.

Based on the formula, we will need to get the opposite side of the triangle which is length BC for us to be able to determine sinA since the hypotenuse is given.
