You can find the value of x using the trigonometric function of cosine.
cos x = adj/hyp
cos 49 = x/55
55(cos 49) = x
36.083 = x
Hope I am right :)
It is equal to 9.461 x 10 km
20% of 124.95 is close to $125 so that is equal of 12.50 of 10% so multiply by 2 which is $25.00 so the estimate discount of the jacket will be $25.00
Number 2 is already a mixed number. But it says mixed number as a decimal. So -1 29/40 as a decimal is -1.725.
The answer would be 26 because .1-4 rounds down, 5-9 rounds up
