From the concepts and properties of triangles, m∠BDC is 26°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the sum of all the interior angles in a triangle is equal to 180°.
In the given ΔABD, line segment AD and BD are equal and hence it is an isosceles triangle.
Therefore,
x° + x° + 70° = 180°.
2x° = 110°.
x = 55°.
So, m∠DAB = m∠DBA = 55°.
We know the sum of linear pair of angles is 180°.
Therefore, m∠ABD + m∠DBC = 180°.
55° + m∠DBC = 180°.
m∠DBC = 125°.
Now,
m∠BDC + m∠DCB + m∠CBD = 180.
m∠BDC + 29° + 125° = 180°.
m∠BDC = 26°.

The Venn diagram shows the results of two events resulting from rolling a number cube.
Events C and D are____.
conditional and dependent
independent
dependent
conditional
Answers
Events C and D are conditional and dependent events.
What can we say about events C and D?By looking at the Venn diagram, we can see that C is the event where the outcome of the dice is even.
While D is the event where the outcome is odd.
So events C and D have no common elements.
Now, the value of these events is related in any way?
if C is true (the number is even) then D must be false.If C is false, then D must be true.Then the events are dependent and conditional, the correct option is the first one.

sum of 12.5 and product of 36
I mean 2 variables add up to 12.5
and multiply to 12.5
(x+y)=12.5
X ×Y=36
What is value of x and y
Answers
Answer:
(4.5, 8) and (8, 4.5)
Step-by-step explanation:
Given the equations
(x+y)=12.5 ... 1
X ×Y=36 .... 2
From 2, Y = 36/X
Substitute into 1
x+ 36/x = 12.5
x^2 + 36 = 12.5x
x^2 - 12.5x + 36 = 0
10x^2 - 125x + 360 = 0
2x^2 - 25x + 72 = 0
Factorize
2x^2 - 16x - 9x + 72 = 0
2x(x-8)-9(x-8) = 0
2x-9 = 0 and x-8 = 0
x = 9/2 and x = 8
when x = 9/2
Y = 36/(9/2)
Y = 36 * 2/9
Y = 8
When x = 8
Y = 36/X
Y = 36/8
Y = 4.5
Hence the solutions are (4.5, 8) and (8, 4.5)

A bus traveled 330 miles between two cities. If the bus traveled for 6 hours, how
many miles did the bus travel per hour?
Answers
Answer:
55 miles per hour
Step-by-step explanation:
.......ur welcome.......
330÷6=55
we divide the amount of miles by the time it took the bust to travel
A bus traveled 330 miles between two cities. If the bus traveled for 6 hours,, The bus will travel approximately 55 miles per hour.
To determine the number of miles the bus traveled per hour, we need to divide the total distance traveled by the time taken.
Given:
Total distance traveled = 330 miles
Time taken = 6 hours
To find the miles per hour, we divide the total distance traveled by the time taken:
Miles per hour = Total distance traveled / Time taken
Miles per hour = 330 miles / 6 hours
Miles per hour ≈ 55 miles per hour
Therefore, the bus traveled approximately 55 miles per hour.

Alex records the running time—the number of minutes a movie lasts from start to finish—of 50 popular movies. The distribution of times, in minutes, is displayed in the histogram below.
Answers
Answer:
You forgot to attach the question and the histogram.
Is your question “the interval containing the most movies” ? If yes, then the answer is :
Interval 90-100 minutes
Step-by-step explanation:
A histogram is a chart that is used to represent data in form of bars.
Like every other chart, it consists of both the x and y axis. The y axis contains the frequency or percentage of occurrences while the x axis contains the range or intervals.
To determine the interval with the most occurrences, that is the interval containing most movies, we look for the bar with the most height. The bar that is tallest amongst others has the most movies in its running time.
From the attached histogram, the interval containing the most movies is the 90- 100 minutes interval.
This simply means that from Alex’s record, out of the 50 popular movies, more movies run with the 90-100 minutes interval.
PS: view the attached histogram
