hypotenuse is the longest side on a triangle.

so the angle is 76 and the side(hypotenuse) is 96.0m. you are missing some other values.

you know the other angle is 14 by the pythagreon theorem (180 - (76 + 90) = 14).  knowing that you can set up the equation cos14 = x/96 (hopefully you have learned to use cosines) which can also be written as 96cos14 = x by multiplying each side by 96. by typing that into your calculator you get 13.13 meters

No I am not missing values, thats the question. The awnser is 93.14 but I dont have it written down how I got there and I dont remember how. I used sin to solve it though.What I have written down is: H over O (sin) and then x over 96.0 = 93.14. Its grade 10 math (studying for the exam)

We can use the sine here

 

sin [76° ] = h / 96    →   96 * sin [76° ]  = h  ≈ 93.15 m 

 

 

cool cool cool
