First find the length of the hypotenuse using pythagorean theorem
<span>c^2 = 5^2 + 7^2
c^2 = 25 + 49
c^2 = 64
c=8 (take the square root in both sides)
Since sin = opposite/hypotenuse,
sin = 5/8 = 0.625</span>
Exact form:
22/13
Mixed number:
1 9/13
I believe it is 56 because 7•8 is 56 and 1•56 is 56
I used the cross product method
5x = 2.4 •3
5x=7.2
7.2divided by 5

Hope I helped
