Answer 1

hlo mate ✌️

Short cut Formula:

$= > \frac{</strong><strong>PBP</strong><strong>}{</strong><strong>HHB</strong><strong>}$

where :

p = perpendicular

h = hypotenuse

b= base

Hope it helps ❣️

Answer 2

Answer:

The following sentence:

"Some People Have Curly Black Hair and Tan Painted Black."

The first letters of the words of the sentence are s, p, b, c, b, h, t, p, b

here, s for sin and sin=p/b

then, c for cos and cos=b/h

and, t for tan=p/b

in order of the first letters.

For ratio by angles

0. 30. 45. 60. 90

sin. 0/4. 1/4. 2/4. 3/4. 4/4

cos. 4/4. 3/4. 2/4. 1/4. 0/4

tan. 0/4. 1/3. 2/2. 3/1. 4/0

In the above chart , find the square root of the given values and that will be the value for that angle.

As you can see, the numerators are for sin in ascending order and for cos in descending order

and for tan the numerator is in ascending while the denominator is in descending order.
