You need to use the law of cosine:
B^2 = A^2 + C^2 - 2ACcos(b)
55^2 = 90^2 + 50^2 - 2(50)(90)cos(b)
0.841666 = cos(b)
b = 32.68
The probability is about 68% but you just got coconut malled
2/3 / 8/7 flip the second fraction and multiply straight across
2/3 x 7/8 2 x 7 = 14
3 x 8 = 24 so you have 14/24 if you need to simplify, since both numerator and denominator are even so divide by 2. Which gives you 7/12
Hope this helps you :)
<u>Answer-</u>
<em>Equation 1</em><em> is the equation which represents the graph.</em>
<u>Solution-</u>
From the graph it can be noticed that, the function is a hyperbola. It is a rectangular hyperbola.
The general form of rectangular hyperbola is,

Where c is a constant.
Equation 1 represents a function of rectangular hyperbola, with vertical asymptote as x=-2 .
Equation 2 represents an exponential function.
Equation 2 represents an cubic function.
Equation 2 represents logarithmic function.
Therefore, equation 1 is the equation which represents the graph.
15.5, because 31 divided by 2 is 15.5. And all the other number divided by the number below them also turns out to be 15.5.
Hope this helps. :)
