4≤x/2.1
To Solve
Multiply by 2.1
8.4≤x
Answer:
36.50
To two decimal places
Step-by-step explanation:
The hypothenuse side in a right angle triangle has 58cm. While the angle touching one of its leg is 51°. How long is that leg.
From the right angled triangle, the size of the leg touching the hypothenuse is the adjacent side of the triangle, hence in trigonometry, the cosine rule is used, because it involves the adjacent and the hypotenuse.
Cos 51°=x/58
Let the size of the leg be x
Making x the subject
x=58(Cos51°)
x=36.500058
Correct to two decimal place
x=36.50
The function is:
Now to put in the form Ax+By=c we hace to let the number that don't have x ot y in the left side of the equation anthe the rest of the term in the right side of the equation:
where:
Answer:
Look at the photo
Step-by-step explanation:
I hope I solved it right. Once you get the main concept of it, it's pretty easy.
If you have any questions about the way I solved it, don't hesitate to ask
Time = distance / speed
Samma : 200/25.98 = 7.70 meters per second
Tom : 100 / 12.54 = 7.97 meters per second
so the faster runner is Tom
