Answer 1

which one do u think it is

Answer 2

ok, so F is a 90* angle and the measurements of a triangle =180*

Answer 3

because you're wanting to know the angle measure of a, you know the opposite side and the adjacent side, so, which of sine, cosine, and tangent would you use

Answer 4

i dont know.... im bad with these...

Answer 5

do you know
soh
cah

no..

Answer 7

well
sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent
and becuase we want opposite/adjacent, which one are we going to use

tan(x)?

Answer 9

yes

Answer 10

so, like how i wrote it
what would the equation be like

Answer 11

Ok, what you want to do issss:

start with what we know: angle measure of F = 90* right angel right?

So since we are finding the angle measure of A, we will have to use one of those formulas that @snowflake0531 is telling you about.

Answer 12

tan(a)?

Answer 13

yes!
so tan(a) = what

Answer 14

remember, tan(a) = opposite/hypotenuse
so, what is it

Answer 15

anyways lol
tan(a) = 30/55
so, i recommend putting
tan^-1 (30/55) into your calc

good job - congrats !

Answer 17

tan(A)=30/55

Answer 18

ope so it sent late-

Answer 19

so now put it into mathway or something
tan(x) = 30/55
and figure out what the angle is

it says .6?

Answer 21

im so confused...

Answer 22

oh i used the wrong calculator. mathway is blocked-
