where b is the base length and h is the height (b and h on the triangle will always be perpendicular to each other)
Plug in 75.6 m as b and 42 m as h

I hope this helps!
2v=3-7
2v=-4 divide both sides
v=-2
Make the 3 into a fraction and then flip it to cancel out which makes it easier then do it to the -2,197 for you to get x
