Answer:
sinΘ = 
Step-by-step explanation:
sinΘ = 
The opposite is 24, but we require the hypotenuse h
Using Pythagoras' identity
h² = 7² + 24² = 49 + 576 = 625 ( take square root of both sides )
h = 
= 25
Thus
sinΘ =
1. 8+5=13
2. 13 x 3 x 10 = 13 x 30 = 390
Using the information above transform the ratio 8:5.
8 x 30 : 5 x 30
If you do this, you'll end up with the ratio:
240 : 150
This means that 240 adults attended whilst 150 children attended.
The numeric value of the expression -a² - 2bc - |c| for a = -3, b = -5 and c = 2 is of 9.
<h3>How to find the numeric value of an expression?</h3>
The numeric value of an expression is found replacing each letter by it's attributed value.
In this problem, the expression is:
-a² - 2bc - |c|
The attributed values are:
a = -3, b = -5 and c = 2
Hence the numeric value will be given by:
-a² - 2bc - |c| = -(-3)² - 2(-5)(2) - |2| = -(9) + 20 - 2 = -9 + 18 = 9.
