Question

Need help, pre calc trig problem attached

Answer 1

@Mimi_x3

Answer 2

use sohcahtoa, and pythagorean thm

Answer 3

ok to i think i should have did sin25 = b/25 right?

Answer 4

so i would have:

-0.13 = b/25 then cross multiply?

so:
-0.13/1 x b/25
b = -3.30

right?

@Mimi_x3

Answer 5

@iambatman am i right for b?

Answer 6

hello

Answer 7

-3.30? Seems wrong

Answer 8

I got 10.6

Answer 9

Check if your calculator is in the right mode (should be degree mode, not radians).

Answer 10

Yes, it seems you're on the wrong mode, you should fix that :)

Answer 11

ok :) let me see how to change that one sec

Answer 12

wait do i use sin or tan?

Answer 13

sin theta, opp/hyp

Answer 14

Your steps are right, you just used the wrong mode.

Answer 15

kk i have no idea how to change that let me search for an online calculator

Answer 16

It should say DRG on your calculator

Answer 17

or something

Answer 18

i have a casio fx 9750 g2 calculator

Answer 19

Lol, idk but you can use wolfram I suppose.

Answer 20

lol ok

Answer 21

how do i type it into wolfram? is it 25sin(25) or 25 x sin(25)

Answer 22

i just got 10.56

Answer 23

Yeah :)

Answer 24

so i have b now
let me type this:)

Answer 25

and then i know i can solve a with a^2 + b^2 = c^2 but i need 2 other ways

Answer 26

i can use that right?, i keep getting lost st the 25 x 25 because that would make the hypoth 625

Answer 27

(a.1) a^2 + 10.56^2 = 25^2
a^2 + 111.5136 = 625
a^2 = 625 - 111.5136
a^2 = 513.4864
a^2 = 22.66
@iambatman is that right?

Answer 28

You could also use a similar method as before

Answer 29

so i would use tan as the second way?

Answer 30

SOH CAH TOA

Answer 31

sin= opposite over hypotenuse
cos= adjacent over hypotenuse
tan= opposite over adjacent

csc= the exact opposite of sin
sec= exact opposite of cos
cot= exact opposite of tan

Answer 32

oh i see i would still use cos and tan as the last ones
