Step-by-step explanation:
3 3/4 lb of candy costs $ 20.25
we have been given a mixed fraction with both whole number and fraction
so lets convert it an improper fraction
3 3/4
3 wholes are equivalent to
then 3 3/4 is -
so 15/4 lbs -- $ 20.25
then 1 lb is --
therefore 1 lb is equal to $ 5.40
<u>Given</u>:
Given that Corey is flying a kite with 105 meters of string.
The string makes an angle of 42° with the ground level.
We need to determine the height of the kite.
<u>Height of the kite: </u>
The height of the kite can be determined using the trigonometric ratio.
Thus, we have;
From the given data, the values are , opp = h (height of the kite) and hyp = 105 meters.
Substituting the values, we get;
Multiplying both sides of the equation by 105, we get;
Rounding off to the nearest meter, we get;
Thus, the height of the kite is 70 meters.
Check the picture below.
we know that the arcST is 30°, meaning the inscribed angle intercepting it will be half that or 15°.
in the triangle RWT, two sides of it are RT and RW, both of which are radius segments and thus equal, meaning that triangle RWT is an isosceles, and in an isosceles the twin sides also make twin angles, meaning that ∡RTW is a twin of the inscribed angle ∡RWT.
