Answer:

y = (√7)/4

Step-by-step explanation:

The equation of the unit circle is ...

x^2 +y^2 = 1

Putting the given value in for x, we can find y to be ...

(-3/4)^2 +y^2 = 1

y^2 = 1 -(-3/4)^2 = 1 -9/16 = 7/16 . . . . . subtract 9/16

y = √(7/16) . . . . . . . . . . . take the square root; y > 0 here

y = (√7)/4

I will give BRAINLIEST to the correct answer Find the measure of angle 1

m_a_m_a [10]

Answer:

angle 1=94 degree

Step-by-step explanation:

-x + 106=5x + 34 (they are alternate interior angles)

106-34=5x+x

72=6x

72/6=x

12=x

substitute the value of x in 5x + 34

5*12 + 34

60+34

Now,

angle 1 =5x +134 ( they are vertically opposite angles)

angle 1=94 degree

Which equation represents the line that is perpendicular to and passes through (-12,6)?.

Evgesh-ka [11]

The equation that represents the line that is perpendicular is

3y + 5x = -42

The standard equation of a line in point-slope form is expressed as:

$y-y_1=m(x-x_1)$

m is the slope of the lne

(x1, y1) is any point on the line.

Given the equation y = 3/2x + 1, the slope of the line is 3/5

The slope of the line perpendicular is -5/3

Substitute the point (-12, 6) and the slope m = -5/3 into the equation above to have:

$y-6=-5/3(x-(-12))\\3(y-6)=-5(x+12)\\3y-18=-5x-60\\3y = -5x - 60 + 18\\3y + 5x = -42\\$

Hence the equation that represents the line that is perpendicular is

3y + 5x = -42
