If mZDAB = 32°, what is mZBDC?
(1) 320
(3) 58°
(2) 520
(4) 64°
Answers
Answer:
it will be (3)
Step-by-step explanation:
since DB is a median
then DB= half AC , AB=BC
then AB=BD
then the two triangles are isosceles
The required m∠BDC is 32° .
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid.
According to the given question ;
DB is a median;
By the symmetry ;
Then DB = half AC ,
= AB = BC
Then= AB = BD
In a triangle, a line that connects one corner (or vertices ) to the middle point of the opposite side is called a median. A property of isosceles triangles, which is simple to prove using triangle congruence, is that in an isosceles triangle the median to the base is perpendicular to the base.
Then the two triangles are isosceles.
Means m∠DAB = m∠BDC = 32°

This means that angle 1 and angle 2 add up to 180 degrees. You can put them into an algebraic problem like I have in this (the image I have added), and solve for what x is. That is the key to finding out what angle 1 equals!
Once you have found x you can plug it into the equation you have for angles 1 and 2 to find if they equal 180.

Micah vacationed on a Caribbean island in the summer at a luxury hotel. He spent an entire day on a sightseeing excursion that explored the beautiful scenery of the city. Those who went on the trip boarded a bus which went 15mph through a 30 mile section of the city's countryside. There was a lunch stop at a local eatery before the group continued on a 3 hour tour of the city’s sights at a speed of 10mph. Lastly, the bus left the city and travelled 40 miles back to the hotel. Micah arrived back at the hotel exactly 2 hours after leaving the local eatery. What was the bus’s average rate for the entire trip?
Answers
Answer:
The bus's average rate for the entire trip is approximately 14.29 mph
Step-by-step explanation:
The given information are;
The speed of the bus through the 30 mile section = 15 mph
The time the bus moved at 10 mph = 3 hours
The distance the bus travelled back from the city = 40 miles
The time Micah arrived back at the hotel after leaving the local eatery = 2 hours
Assuming Micah correctly arrived back at the hotel after leaving the city = 2 hours
We have;
Total distance = 30 miles + 3 hour × 10 mph + 40 miles = 100 miles
Total time = 30 miles/(15 mph) + 3 hours + 2 hours = 7 hours
The average velocity = Total distance/(Total time) = 100 miles/(7 hours) ≈ 14.29 mph.
The bus's average rate for the entire trip ≈ 14.29 mph.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
3x + 5 = 4 is an expression.
We have,
V = 1/3 lwh
Multiply 3 on both sides.
3V = lwh
Divide both sides by lh.
3V / lh = w
w = 3V/lh
Thus,
V = 1/3 lwh
The value of w is 3V/lh

The carrier has more mass by the amount of ...
7.3×10^7 -0.998×10^7 = (7.300 -0.998)×10^7 = 6.302×10^7 . . . kg
