Answer:

Step-by-step explanation:

This question is a bit sloppy. In higher math courses it would not be permitted. I'll give you the general rule that applies to this question -- sort of.

If you have a triangle that hast angles of 100 50 and 30

The largest side will be opposite the 100 degree angle.

The smallest side will be opposite the 30 degree angle.

So for the question, you are intended to say that CD > AB because CD is opposite a 43 degree angle and AB is opposite a 40 degree angle.

So the answer is Since 43 > 40 then CD>AB

1. Use the image of the circle to identify the length of the radius, diameter, and circumference. Leave all answers in terms of

Grace [21]

Answer:

Radius = r = 7.5

Diameter = d = 15

Circumference = C = 15π

Step-by-step explanation:

We are given the image of a circle with a straight line passing through the center of the circle and touching its edges. Such a line is known as the diameter of the circle. From the image we can see the length of the diameter of the circle is d = 15 units.

Radius is define as half of the diameter. Since the diameter is 15 units, the radius of the given circle will be half of 15 which is r = 7.5 units.

Circumference of the circle = C = 2πr

Using the value of radius(r), we can write the circumference as:

C = 2π(7.5) = 15π

What is the value of x

Nadya [2.5K]

35 + 58 = 93, since all angles in a triangle are equal to 180 you can do 180 -93 to get the third angle, which is 87. Since x is in an exterior angle, 87+x =180. From there its simple. Subtract 87 on each side and you get x = 93.

What is the value for y? Enter your answer in the box. y =

MArishka [77]

The given triangle has two sides marked equal and hence is an isosceles triangle.In isosceles triangle base angles are equal <A=<B=50.

Sum of angles in any triangle is 180 degrees.

<A+<B+<C=180°

50+50+5y+10=180

Adding like terms :

110+5y=180

Subtracting 110 on both sides:

5y=70

Dividing both sides by 5:

y=14.

PLEASE HELP Which of the following are true if event A and B are independent

makkiz [27]

Answer:

a) $P(B/A) = P(B)$

Step-by-step explanation:

Step(i):-

Given that A and B are independent events

P(A∩B) =P(A) P(B)

we will use the conditional probability

$P(A/B) = \frac{P(AnB)}{P(B)}$

$P(B/A) = \frac{P(AnB)}{P(A)}$

Step(ii):-

Given that A and B are independent events

P(A∩B) =P(A) P(B)

$P(B/A) = \frac{P(AnB)}{P(A)}$

$P(B/A) = \frac{P(A)P(B)}{P(A)} = P(B)$

$P(B/A) = P(B)$
