Question

How do I find the measurement of angle F in this triangle?

Answer 1

you can use trigonometric functions:
tagF=12/5
sinF=12/13
cosF=5/13

use calculator to solve these

Answer 2

i dont understand @AlexandervonHumboldt2

Answer 3

dont understand what?

Answer 4

what function do i use bro

Answer 5

you can use any of these 3

Answer 6

what kind of calculator do you have @TangerineSkyys ?

Answer 7

ive just been using the calculator on my phone. Should it be in degree or rad?

Answer 8

it depends on what your book wants, but probably degrees

Answer 9

does your calculator on your phone have trig functions (sine, cosine, tangent) ?

Answer 10

im not getting any results this sucks. yes it does

Answer 11

ok how about the inverse trig functions?

Answer 12

yea

Answer 13

ok so what you do is pick any of the three equations @AlexandervonHumboldt2 wrote out, let's pick on the sine one

sin(F) = 12/13

apply the arcsine function to both sides to get

arcsin(sin(F)) = arcsin(12/13)
F = arcsin(12/13)

to evaluate `arcsin(12/13)` you will use inverse sine

Answer 14

i got 67?

Answer 15

idk how your calc works, but usually there's a "2nd" key or "inverse" key

so you may say "2nd", then "sin" then 12/13

Answer 16

you should get `arcsin(12/13) = 67.3801350519596` roughly

Answer 17

Awesome, thanks for your help i really do appreciate it

Answer 18

angle F is roughly 67.3801350519596 degrees

Answer 19

you can use the other equations @AlexandervonHumboldt2 wrote out just use different inverse trig functions
