the value of sin ∅ is 12/ 13
<h3>Quadrants and the "cast" Rule:</h3>
- In the first quadrant, the values for sin, cos, and tan are positive.
- In the second quadrant, the values for sin are positive only.
- In the third quadrant, the values for tan are positive only.
- In the fourth quadrant, the values for cos are positive only.
From the given question,
We have, cos ∅= 5/13
From the trigonometric identities, we have that
Then , let's substitute the value of cos ∅
Let make sin the subject of formula and find the squares of the fraction
sin²∅ =
Find the LCM
sin²∅ =
Find the difference
sin²∅ =
Find the square root
sin∅ =
sin∅ =
In quadrant II , sin is positive, so we have
sin ∅ = 12/ 13
Thus, the value of sin ∅ is 12/ 13

Area of Square Formula: A = s²
- <em>s</em> is the side length
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
A = 225 in²
<u>Step 2: Solve for </u><em><u>s</u></em>
- Substitute in variables [Area of a Square Formula]: s² = 225 in²
- [Equality Property] Square root both sides: s = 15 in
Answer:
That would be 9 my good sir ( or ma'am )
Step-by-step explanation:
basicly round the 61 so that there would not be a remainder and divide 54 by 6 you will get 9, so therefore the same case is for 540 by 60.
