The width and length of this rectangle are 3 7/12cm and 4 1/12cm respectively.
Hope this helped! ^v^
Answer:
Step-by-step explanation:
We are given that,
The acute angle of the right angled triangle is 65°.
Length of the side opposite to the acute angle = f
Length of the side adjacent to the acute angle = d
Length of the hypotenuse = e
Using 'Pythagoras Theorem', which states that 'the sum of square of length of the sides of a right triangle is equal to the square of the length of the hypotenuse'.
i.e.
i.e.
i.e.
As, the length of the hypotenuse cannot be negative.
So, the expression showing the value of e is .
What I did to start with was to find the lowest number that both 12 and 10 could divide into, that number is 60.
I know 60 divided by 12 is 5 and I know that 60 divided by 10 is six.
Then I took 5 and multiplied it by 3 and got 15. I did this step because you need 5 packages of cups and each package cost 3 dollars.
Next I took 6 and multiplied it by 5 and got 30. I did this step because you need 6 packages of plates and each package cost 5 dollars.
You would then take 30 dollars and 15 dollars and add them together to get your total.
The answer is 42 dollars.
there should be a cross multiplication
3(8x)=2
expanding bracket
24x=2
multiple both sides by 24
x=1/12
