Answer:
60 degrees.
Step-by-step explanation:
We use trigonometry of a right angled triangle:
Adjacent side = 20 ft, Hypotenuse = 40 ft.
cos x = adjacent / hypotenuse = 20/40 = 1/2
x = 60 degrees.
Answer:
0.512 = 51.2%
1.94 = 194%
0.9 = 90%
1.33 = 133%
1.14 = 114%
1.42 = 142%
Step-by-step explanation:
To convert a decimal to a percent, move the decimal point two spaces to the right.
Converting a percent to a decimal works the same way, except you move the decimal two spaces to the left.
[Note: If there aren't enough numbers to go over two spaces, place a zero at the end. For example, if you have 0.9, and you need to convert it into a percent, you'd place a zero after the 9, making it 0.90.]
So if y= 7 you plug in the variable into the equation.
3(7-5)
3(2)
6
The answer is 6. I hope this helps love!:)
