For each angle θ listed below, find the reference angle α, and then find sin θ. Round sin θ to four decimal places, if necessary

babunello [35]

Answer with explanation:

It is given that

$\rightarrow\Theta =132^{\circ}$

The Angle lies in Second Quadrant.

Formula to find reference Angle

→If Angle lies in first Quadrant

then Reference Angle = The Angle given

→If Angle lies in Second Quadrant

Then Reference Angle = 180° - Angle

→If Angle lies in third Quadrant

then Reference Angle = Angle - 180°

→If Angle lies in fourth Quadrant

Then Reference Angle = 360° -Angle

Reference Angle

$=180^{\circ}-132^{\circ}\\\\=48^{\circ}$

⇒sin 48°=0.7431448

Rounding to four decimal places

Sin 48°=0.7432

Answer:

y - 11 = 7(x - 3)

y - 11 = 7x - 21

y = 7x -10

What is the equation of the line in slope-intercept form? Line on a coordinate plane. The line runs through points begin ordered

Marrrta [24]

Find the equation of the line connecting (0, 5) and (-2, 0).

As we go from the first point to the second, x decreases by 2 and y decreases by 5. Thus, the slope of this line is m = rise / run = -5/(-2), or 5/2.

Starting with the general equation of a line in slope-intercept form, y = mx + b, substitute the knowns as appropriate to determine the value of b:

y= mx + b => 5 = (5/2)(0) + b. Then b = 5, and the desired equation is

y = (5/2)x + 5.

Check this! If we subst. the coordinates of (-2,0) into this equation, is the equation true?

0 = (5/2)(-2) + 5

Yes. So, y = (5/2)x + 5 is the desired equation.
