What is a trapezoid?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezoid, one pair of opposite sides are parallel.
In the isosceles trapezoid, the sum of opposite angles will be equal to 180°. Then the equations are given as,
∠A + ∠C = 180°
Then the measure of the angle ∠A is calculated as,
∠A + 75° = 180°
∠A = 105°
The measure of the angles ∠A will be 105°. Then the correct option is B.

Graph the equation y = 4x + 6.
Answers
All three points displayed are on the line. Find an equation relating x and y.
Answers
Answer:
y = 2x - 3
Step-by-step explanation:
The graph is a straight line, thus linear with equation
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 3) and (x₂, y₂ ) = (6, 9) ← 2 points on the line
m = [tex]\frac{9-3}{6-3}[/tex] = [tex]\frac{6}{3}[/tex] = 2 , thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 3 ), then
3 = 6 + c ⇒ c = 3 - 6 = - 3
y = 2x - 3 ← equation relating x and y
The equation whigh relates x and y points on the graph can be expressed in slope-intercept form as y = 2x - 3
The general form of a slope - intercept equation is :
y = bx + cb = slope ; c = interceptSlope, b = Rise / Run
Rise = 9 - 3 = 6 Run = 6 - 3 = 3Slope, b = 6/3 = 2
Taking a pair of point on the graph :
(3, 3)
3 = 2(3) + c
3 = 6 + c
3 - 6 = c
c = - 3
Therefore equation can be expressed thus :

if you have 3 gallons of 95% alcohol, how much pure water should be added to be able to produce 70% alcohol?
Answers
Answer: Approximately 1.0714 gallons
===========================================
Work Shown:
x = amount of pure water
3 gallons of 95% alcohol means you have 3*0.95 = 2.85 gallons of pure alcohol.
If we add on x gallons of pure water, we'll have 3+x gallons of solution
So we'll have 2.85/(3+x) representing the ratio of the amount of pure alcohol to total solution. Set this equal to 0.70 and solve for x
2.85/(3+x) = 0.70
2.85 = 0.70(3+x)
2.85 = 0.70(3)+0.70(x)
2.85 = 2.10+0.70x
2.85-2.10 = 0.70x
0.75 = 0.70x
0.70x = 0.75
x = 0.75/0.70
x = 1.07142857142858 which is approximate
x = 1.0714
So if you add about 1.0714 gallons of pure water, you'll go from 95% alcohol to 70% alcohol.

Jane took a train traveling at an average speed of 60 mph from Boston, MA to Washington, D.C. The trip took 8 hours. On her way back to Boston, Jane decides to take an express train that travels at an average speed of 75 mph. How long will the trip home take?
Answers
Answer:
6.4 minutes
Step-by-step explanation:
The question gave us the following details:
Average speed = 60mph
Time spent on trip = 8 hours
Average speed of express train on way back = 75mph
T = distance/speed
D = distance
V = speed
T = d/v
d = v(t)
d = 60 x 8
= 480
Such that
480/75
= 6.4 hours.
That is 6 hours 40 minutes is the length of time it would take on the trip home.

Which values of x are point(s) of discontinuity? x = –6 x = –2 x = 0 x = 2 x = 4.
Answers
Discontinuity is the value of x or y for which the function is not defined. The function is discontinued at points x=0 and x=4.
What is discontinuity?The discontinuity is the value of x or y for which the function is not defined. It is represented by a blank dot at the point at which it is not defined.
The discontinuity of the function is represented by a blank dot, and it is the point where the function is not defined.
If we look in the graph, we will find that there are three blank dots, which are at:
x = -2
x = 0
x = 4
Now, since discontinuity means that the function is not defined but as we can see that the value of the function is defined at x = -2, therefore, we are left with only two options which are x=0 and x=4.
Hence, the function is discontinued at points x=0 and x=4.
