Answer:

x = 55°

Step-by-step explanation:

Hello!

The sum of angles in a triangle is 180°.

To solve for x, we have to subtract the given angles from 180°.

<h3>Solve for x</h3>
  • 180° = ∠1 + ∠2 + ∠x
  • 180° = 75° + 50° + x°
  • 180° - 75° - 50° = x°
  • 55° = x°

The value of x is 55°.

<u>Angle sum property of a triangle</u>

  • Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

∠A + ∠B + ∠C = 180°

  • ∠A = ?
  • ∠B = 75°
  • ∠C = 50°

We need to find the value of ∠A

According to the angle sum property of a triangle

⇢∠A + ∠B + ∠C = 180°

⇢∠A + 75° + 50° = 180°

⇢∠A + 125° = 180°

⇢∠A = 180° - 125°

⇢∠A = 55°

Answer:

y = -5x - 19

Step-by-step explanation:

y = mx + b

m = -5    Point: (x , y)      (-3 , -4)

b = y - mx = -4 - ((-5) * (-3)) = -4 - 15 = -19

equation: y = -5x - 19
