Question

I have no clue how to do this!!!

Answer 1

We can use trigonometric formulas to solve this question. Let's use cosine, since we can use the adjacent side and hypotenuse and solve for the hypotenuse:

We need to convert degrees to radians via the equation: $1degree= \frac{ \pi }{180}$

So 20 degrees converted to radians is: $20* \frac{ \pi }{180}= \frac{ \pi }{9}=0.349$

So now we use the equation:

$cos(0.349)= \frac{35}{y}$

$y= \frac{35}{cos(0.349)}$

$y=37.25$

So the length of the hypotenuse is 37.25.
