Answer:

$cos^2\theta + sin^2\theta = 1$

Step-by-step explanation:

Given

$(\frac{b}{r})^2 + (\frac{a}{r})^2$

Required

Use the expression to prove a trigonometry identity

The given expression is not complete until it is written as:

$(\frac{b}{r})^2 + (\frac{a}{r})^2 = (\frac{r}{r})^2$

Going by the Pythagoras theorem, we can assume the following.

a = Opposite
b = Adjacent
r = Hypothenuse

So, we have:

$Sin\theta = \frac{a}{r}$

$Cos\theta = \frac{b}{r}$

Having said that:

The expression can be further simplified as:

$(\frac{b}{r})^2 + (\frac{a}{r})^2 = 1$

Substitute values for sin and cos

$(\frac{b}{r})^2 + (\frac{a}{r})^2 = 1$ becomes

$cos^2\theta + sin^2\theta = 1$

$\huge \bf༆ Answer ༄$

Let's solve this using unitary method ~

$\sf3 \: seconds = 63 \: meters$

$\sf1\: second= 63 \div 3 \: meters$

$\sf1\: second= 21 \: meters$

$\sf5\: seconds= 21 \times 5 \: meters$

$\sf5\: seconds= 105 \: meters$

Therefore , the ostrich will run 105 meters in 5 seconds.

Mila [183]

Answer:

Step-by-step explanation:

Express this time interval in set notation:

15 ≤ t ≤ 20

This says that the waiting time will be between 15 and 20 minutes.
