Answer:
so you are going to use tangent because tan is opposite over hypotenuse
Step-by-step explanation:
this is how it should look
tan 40=x/25
plug into your calculator tangent, then 40( you should get 0.8390996312)
so it should look like(on paper) 0.8390=x/25
then you are going to cross multiply 0.8390 because we don't know what x is so when we multiply it should tell us
it now should look(again all on paper) 20.7749=x
