Answer:

2.4 m

Step-by-step explanation:

sin(A) = opposite/hypotenuse

Using the bigger triangle:

sin(A) = 4/5

Using the smaller triangle:

sin(A) = X/3

4/5 = X/3

X = 4/5 × 3

X = 2.4m

Evaluate cot870°. 1. - sqrt3 2. -1/sqrt3 3. 1/sqrt3 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.

Find an equation of the line perpendicular to the graph of 14x-7=1 that passes through the point at (-2,4)

wolverine [178]

we know that

If two lines are perpendicular, then the product o their slopes is equal to minus one

$m1*m2=-1$

Step 1

Find the slope of the given line

we have

$14x-7=1\\14x=1+7$

$x=8/14$ -------> $x=4/7$

This line is parallel to the y-axis

the perpendicular will be parallel to the x-axis

Step 2

The equation of the line perpendicular to the given line is the y-coordinate of the given point

Point $(-2,4)$

the equation is

$y=4$

therefore

the answer is

$y=4$

see the attached figure to better understand the problem
