I believe your answer would be c.
Answer:
The measure of angle A is 115°
Step-by-step explanation:
we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
so
∠C+∠A+∠B=180°
substitute values and solve for x
x°+(3x-35)°+(x-35)°=180°
5x°=180°+70°
x=250°/5=50°
Find the measure of angle A
∠A=(3x-35)°
substitute the value of x
∠A=(3(50)-35)=115°

Answer:
D
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 m use the slope formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 6) and (x₂, y₂ ) = (8, 4)
m = 
= - 
, hence
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 4), then
4 = - 
+ c ⇒ c = 4 + = 
y = - x + ← equation of line
