Ok, so for this problem you want to get Y all by itself.
First you’ll want to move your X variables to one side. You do that by adding 2X to both sides of the equation. This will cancel out the -2X and it will turn the 16X into an 18X.
You’re equation is now,
18X+9=9Y
Next you’ll want to divide both sides by 9 so that you’ll get Y all by itself.
Your equation should look like this.
Y=2X+1!
And that’s your answer:) I hope this helped!
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
