Since the quadrilateral is inscribed inside the circle, where the four vertices are on the circle itself, this means that the opposite angles add to 180 degrees.

Angle I and Angle D are opposite angles. They add to 180 degrees

(angle I) + (angle D) = 180
(45 degrees) + (angle D) = 180
(angle D) + 45 = 180
(angle D) + 45 - 45 = 180 - 45 ... subtract 45 from both sides
angle D = 135

The measure of angle D is 135 degrees

Which is not a justification for the proof?
Dimas [21]
There are no marks to conclude that the sides of the triangle are congruent, it doesn't mean they're not, it just means there is a chance that the side-side-side is out. I am not sure if the AB=C is referring to the angles A, B and C, or if it referring to line segment AB.

A raft travels downriver at a rate of 6 miles per hour. The total distance d in mile that the raft travels is equal to the rate
matrenka [14]

Answer:

Dependent variable: total distance (d)

Independent variable: number of hours (h)

Equation: d = 6h

Step-by-step explanation:

In this case given, the dependent variable, total distance (d), is dependent on the independent variable, number of hours (h). This is because, a change in the value of h leads to the change in the value of d. In order words, total distance (d) is a function of the number of hours (h).

Therefore:

Dependent variable: total distance (d)

Independent variable: number of hours (h)

Rate: 6 miles/hr

Equation: d = 6h

Find the circumference of a circle if the area is 45m^2
ki77a [65]
C=2pir
A=pir^2
45=pir^2
divide both sides by pi (aprox pi=3.141592)
14.32394785=r^2
sqrt both sides
3.784699176=r
sub
C=2pir
C=(2)(pi)(3.784699176)
aprox pi=3.141592
C=23.779961311m
