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
Answer:
12 hours
Step-by-step explanation:
1 hour = $7.50
x hours = $90
x hours = 90/7.5
= 12 hours
The volume of a cylinder is given by πr²h
r= x-3, while h =2x+7
Thus; volume = π(x-3)²(2x+7)
=π(x²-6x+9)(2x+7)
=π( 2x³-12x²+18x +7x²-42x+63
= π(2x³-5x²+24x+63) cubic units
Answer:
Uh, I'm assuming you are trying to to say how much feet there was? If not im terribly sorry, But the feet walked would of been 399 If this is not what the question was, Please ignore my comment.
Step-by-step explanation:
To get the answer You need to subtract 566 from 965 and that makes 399 or -399
