How do you solve for x using trig?

Step-by-step explanation:

in trig there are three functions: sin, cosine, and tan

when using trig, you are supposed to pick one angle to make the equation according to

sin= opposite ÷ hypotenuse

cosine= adjacent ÷ hypotenuse

tan= opposite ÷ adjacent

For example 13:

make the equation according to angle 41

you have the adjacent side and opposite side, so use the tan function

tan(41) =

move x so that it becomes a numerator by multiplying both sides by x:

(x) tan(41) = 4

divide both sides by sin(41): x = 4 ÷ tan(41)

plug this into your calculator to get 4.6

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
