<h3>
sin22° = 5/4</h3><h3>
tan22° = 3/√55</h3>
As we know that , sinA = opposite/hypotenuse & tanA = opposite/adjacent
So here we can find sin22° , because they already given the sides opposite & hypotenuse . And we can't find tann22° because they given the value of opposite but not given the value of adjacent side of the angle 22°
Now finding the adjacent side using
Pythagoras theorem :-
• Hypotenuse² = Base² + Height²
=> 40² = Base² + 15²
=> 1600 - 225 = Base²
=> Base² = 1375
=> Base = √1375
=> Base = 5√55
Now ,
- tan22° = Opposite/Adjacent = 15/5√55 = 3/√55
- sin22° = Opposite/hypotenuse = 15/40 = 5/4
Answer: 950 dollars
Step-by-step explanation:
5% of 500 dollars is 25 dollars, so since 5% is 25 dollars, multiply that by how many years he can have it (18). So 18 * 25 = 450. 450 added to the starting 500 dollars is 950 dollars. Your welcome, I'm new so glad I could help.
Answer:
The number of weekday hours are 5.
Step-by-step explanation:
<em>Let the number of weekday hours be "x".</em>
<em>The total week hours are 26, then number of weekend hours is (26-x) .</em>
<em>The charges for weekdays are $2 per hour and for weekends $10 per hour.</em>
The total money spent is $220.
x = 5.
Thus weekday hours utilized are 5 hours, and weekend are (26-5) 21 hours.
