90°
120°
210°
Answer:Answer:
C. 120°
Step-by-step explanation:
m∠d = 150°
m∠ a = 90°
The sum of angles at a point add up to 360°
m∠b + m∠c +m∠e = 360° - (90° + 150°) = 120°
Answer:
y = x +
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 )
To calculate the slope use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (5, 7)
m = = , hence
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
using (5, 7 ), then
7 = + c ⇒ c = 7 - =
y = x + ← equation in slope-intercept form
