So the right angle is equal to 90° and the rest is unknown.
using the triangle sim theorem, which states that all interior angles are equal to 180°.
so it would be x+2x+90°=180°.
then you would need to simply which is 3x+90°=180°
subtract 90° from both sides and get 3x=90°
and then divide both sides by 3 which is 30°
then you would need to find the angle of B which is 2x so you would need to substitute 30° for x which is 60°
the answer is 60°

Answer:
y = - 2x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 8, 22) and (x₂, y₂ ) = (3, 0)
m = =
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 0), then
0 = - 6 + c ⇒ c = 0 + 6 = 6
y = - 2x + 6 ← equation of line
