Answer:

x ≈ 35°

Step-by-step explanation:

Since we don't know the angle, we will replace it with X for now.

Tangent=(\frac{Opposite}{Adjacent})

  • Opposite of X = 12.5 m
  • Adjacent of X = 18 m

tanX = \frac{12.5}{18}

  • Since we are trying to find the angle, we have to subtract "tan\\"

X = tan^-^1(\frac{12.5}{18})

X ≈ 35°

Evaluate cot870°.<br> 1. - sqrt3<br> 2. -1/sqrt3<br> 3. 1/sqrt3<br> 4. sqrt3
ivolga24 [154]

ANSWER

-\sqrt{3}

EXPLANATION

The given angle is 870°.

870°-360°-360°=150°

This means that:

870° is coterminal with 150°, hence its terminal side is in the second quadrant.

It makes an acute angle of 30° with the x-axis.

Note that cotangent is negative in the second quadrant,

Hence,

\cot(870 \degree)  =  \cot(150 \degree)  =  -  \cot(30 \degree)  =  -  \frac{1}{ \tan(30 \degree) }  =  - \sqrt{3}

The first option is correct.

I REALLY NEED SOMEONES HELP ON THIS PLEASE!! I NEED THIS DONE TODAY!
Rufina [12.5K]
The 5 in x - 5 needs to be negative in the table. So, change that and make everything else in that row negative.

You are then left with 3x^2 + x - 15x - 5

Simplify to 3x^2 - 14x - 5
