<h3>Part A:</h3>
  • 1 and 4: Corresponding angles
  • 1 and 3: Vertical angles
  • 1 and 2/2 and 3/2 and 4: Supplementary angles
  • 3 and 4: Alternate interior angles
<h3>Part B:</h3>

With the knowledge that m∠1 = 81°, let's use these relationships to find the rest of the angles:

  • 1 and 3 are vertical: their angle measures are the same, so m∠3 = 81°
  • 1 and 4 are corresponding: their angle measures are <em>also </em>the same, so m∠4 = 81°
  • Finally, 1 and 2 are supplemental: their angle measures add up to 180°, so 81 + m∠2 = 180, making m∠2 = 99°

What is the equation of the line passing through the point (-2,-1) and perpendicular to the line y = 1/2x+5?
uranmaximum [27]

Step-by-step explanation:

the slope of a line is always the factor of x.

here : 1/2

it is the ratio y/x indicating how many units y changes, when x changes a certain angina amount of units when going from one point to another.

a perpendicular slope puts x and y upside-down and flips the sign.

here : -2/1 = -2

so, the equation looks like

y = -2x + b

b is the y-intercept, and we get this by putting the x and y coordinates of the given point into this equation and solve for b :

-1 = -2×-2 + b

-1 = 4 + b

b = -5

the full equation is therefore

y = -2x - 5
