Question

help

Answer 1

do you understand trigonometry?

Answer 2

no ):

Answer 3

well, in a triangle where a angle other than the right angle is theta
\[\sin \theta = \frac{ opposite }{ hypotenuse }\]
\[\cos \theta = \frac{ adjacent }{ hypotenuse }\]
\[\tan \theta = \frac{ opposite }{ adjacent }\]

Answer 4

so its 13.1?

Answer 5

you would want
tan() = (10/44)
if you plug in inverse tan (10/44) into your calculator you would get 12.80426607

Answer 6

damn ok I got it wrong ): you did it right tho what about this one

Answer 7

it can be separated into two triangles
77/2 = 38.5
and one of the triangles would be

find the hypotenuse using a trig function...
which trig function includes the adjacent and hypotenuse?

Answer 8

you would plug in 40/(cos(38.5)) into your calculator

Answer 9

so 51.1

Answer 10

yep :)

Answer 11

help again please haha

Answer 14

I think its either a or b

Answer 15

does this make a line?

Answer 16

yes
