Well 4/4 is equivalent to 1 so do 4/4+3/4
your answer would be 7/4
A) because sometimes you have use smaller numbers like to find a decimal
First you have to find the distance that the gondola is walking. This will be your hypotenuse. To find that you should use the formula for sin: sin(angle) = opposite/hypotenuse.
After your find the distance the gondola is walking you can divide the distance you get by 130 (the distance the gondola walks in a minute) and you'll find your answer.
x/130 = answer<span />
