X = 38°

Step-by-step explanation:

The sum of the inner angles of a triangle is 180 degrees

Then.. :

136+ x= 180

180- 136= x

X= 44

88 + 44 + x = 180

142+ x = 180

X= 180-142

X = 38°

Espero haberte ayudado.

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.
