Let the number be x.

x/3 + 12 = 46

Subtract 12 from both sides and you will get:

x/3 = 34

Multiply both sides by 3:

x = 102

What are the remaining trig functions? and how do i solve for them? pls help

You're told that tan(<em>θ</em>) is positive, but

tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>)

and you're also told that sec(<em>θ</em>) = 1/cos(<em>θ</em>) = -3. So if cos(<em>θ</em>) is negative, sin(<em>θ</em>) must also be negative. In turn, both sec(<em>θ</em>) = 1/cos(<em>θ</em>) and csc(<em>θ</em>) = 1/sin(<em>θ</em>) are also negative.

Now, recall the Pythagorean identity,

cos²(<em>θ</em>) + sin²(<em>θ</em>) = 1

Multiply through both sides by 1/cos²(<em>θ</em>) to get an alternate form of the identity,

1 + tan²(<em>θ</em>) = sec²(<em>θ</em>)

Solve for tan(<em>θ</em>) (which we know is positive):

tan(<em>θ</em>) = √(sec²(<em>θ</em>) - 1) = 2√2

Right away, we get

cot(<em>θ</em>) = 1/tan²(<em>θ</em>) = 1/(2√2) = √2/4

Since sec(<em>θ</em>) = -3, it follows that cos(<em>θ</em>) = -1/3.

Then

tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>)   ==>   sin(<em>θ</em>) = 2√2 × (-1/3) = -2√2/3

and so

csc(<em>θ</em>) = 1/sin(<em>θ</em>) = -3/(2√2)

What I need to know in this question is the answer
RoseWind [281]

Answer:

1.180

2.50

3.56

Step-by-step explanation:

M<4,M<2 and M<5 have to add up to 180 as a result of being a parallel line.

Making m<2 50 since 46°+84=130, 180-130=50.

Since m<1 is 74 and knowing m<2 is 50 74+50=124 180-124=56 m<3=56

Therefore 1,2,3 =180°
