Answer:  DB is 5

Step-by-step explanation:

Alright, lets get started.

Since given that AD is parallel to CB.

And AB is parallel to CD.

And the angle A is given as 90°

It means the given figure is a rectangle.

And the diagonals of the rectangle are equal to each other.

So, DB=AC

So, DB=5

Hence the answer is 5 ...     Answer

Hope it will help :)

A line is drawn on the coordinate plane that passes through the point (3,-6) and has a slope of 4. The y-intercept of the line i
NISA [10]

Answer:

The y-intercept of the line that passes through the point (3, -6) and which has a slope of 4 is -18.

Step-by-step explanation:

We represent the straight line by using this formula from Analytical Geometry:

y = m\cdot x + b

Where:

x - Independent variable, dimensionless.

y - Dependent variable, dimensionless.

m - Slope, dimensionless.

b - y-Intercept, dimensionless.

Now we clear the y-intercept:

b = y - m\cdot x

If we know that x = 3, y = -6 and m = 4, the y-intercept of the line is:

b = -6 -4\cdot (3)

b = -18

The y-intercept of the line that passes through the point (3, -6) and which has a slope of 4 is -18.

Angle M has a measure between 0° and 360° and is coterminal with a –620° angle. What is the measure of angle M?
g100num [7]
Coterminal, first and foremost, means that it ends at the same point that another angle ends. So, we can say that angle M is equivalent to -620°. Now, we can all agree that a circle has 360° in it, so moving an angle 360° in either direction doesn't change where the angle ends, because it just moved one full trip around the circle, and is right back where it started. Overall, we need to put -620° in between 0° and 360° by adding 360° until it's between those two angles:

-620°+360° = -260°
-260°+360° = 100°

Now, 100° is between 0° and 360°, so we can say that angle M must be equal to 100°.
