The sum of angles in a triangle is 180°
So:
(x+7) + (11x-9) +32 = 180
15x +30 = 180
15x = 180-30
15x = 150
x = 150/15
x = 10°
The first is B, but I dont know the answer of the others questions, sorry
Answer:
Mid point of the given end points = 
Step-by-step explanation:
Given the end points of the line segment are :
(0,
) & (
,0)
We will use the mid point formula when two points are: (x₁,y₁) & (x₂,y₂)
mid point = 
now put the value of x₁ = 0
x₂ = 
y₁ = 
y₂ = 0
mid point = 
= 
That's the final answer.
Answer:
Y= -2x +8
Step-by-step explanation:
We know the line is perpendicular so the slope is negative inverse of 1/2, which is -2.
Now to find b, plug into equation
Y= -2x+ b
2= -2(3) +b
2= -6+ b
2+6= b
8=b
