Given: AC bisects angle BCD , Angle ABC is congruent to angle ADC prove AB is congruent to AD. Help immediately
Answer:
Solution given;
<BCA=<ACD
<ABC=<ADC
now
In traingle ABC & ∆ ACD
AC=AC[common base]
<BCA=<ACD[bisector bisect it]
<ABC=<ADC[Given]
∆ABC is congruent to ∆ ACD by S.A.A. axiom
AB is congruent to AD.
[ corresponding sides of a congruent triangle are equal]
Hence proved.
Opposite sides of ∠BAC and ∠CAD is equal BC = DC .
Therefore, AB is congruent to AD.
Given that,
AC bisects angle BCD ,
Angle ABC is congruent to angle ADC
We have to prove,
AB is congruent to AD.
According to the question,
AC bisects ∠BCD,
Angle ABC is congruent to angle ADC
Then, In triangle ABC & ∆ ACD
AC =AC [common base in the triangle]
<BCA = <ACD [bisector bisect it]
<ABC = <ADC [Given]
If one angle between two adjacent sides of a triangle is similar to angle between two sides of another triangle then two triangles are congruent is called SAS-Congruence-Axiom.
Then,
By SAS-Congruence-Axiom
∆ABC is congruent to ∆ACD
AB is congruent to AD. [corresponding sides of a congruent triangle are equal]
Then,
BC (opposite side of ∠BAC) = DC (opposite side of ∠CAD),
BC = DC
Opposite sides of ∠BAC and ∠CAD is equal BC = DC .
Therefore, AB is congruent to AD.
Hence proved.

Answer:
x = 85°
Step-by-step explanation:
As noticed this is a Pentagon (5 sided polygon); therefore to find x, first we have to find the sum of it's interior angles;
Sum of interior angles of a pentagon = (n - 2) * 180°
=> Sum of interior angles of a pentagon = (5 - 2) * 180°
=> Sum of interior angles of a pentagon = 3 * 180
=> Sum of interior angles of a pentagon = 540
Now that we know the sum of interior angles, we can set up the equation and solve for x;
115 + 95 + 115 + 130 + x = 540
455 + x = 540
x = 540 - 455
x = 85

Pls tell me what goes in each box
Step-by-step explanation:
The volume of the cylinder is
V2 = (pi)r^2L
= (3.14)(12.5 xm)^2(50 cm)
= 24531.3 cm^3
The volume of the half cylinder is
V3 = (1/2)(24531.3 cm^3)
= 12265.7 cm^3
If V1 is the volume of the prism then the total volume of the storage chest is
V = V1 + V2 + V3
= 37500 cm^3 + 24531.3 cm^3 + 12265.7 cm^3
= 74297.0 cm^3
an aquarium at the zoo is shaped like a cylinder. it has a height of 4 feet and a base radius of 2.5 feet. the aquarium is being filled with water at a rate of 12 gallons per minute. if one cubic foot is about 7.5 gallons, how long will it take the aquarium to fill? round to the nearest whole minute.
Answer:
49 minutes
Step-by-step explanation:
Volume
v = πr²h
v = π(2.5²)4
v = 78.5 ft³

Answer:
Hi your question is incomplete attached below is the complete question
answer : p ( X < 725 ) = 0.0116
Step-by-step explanation:
Given data:
Average life of bulbs (μ ) = 750 hours
standard deviation (б ) = 55 hours
n ( sample size ) = 25
X = 725
Probability that the mean life of a random sample of 25 bulbs will be less than725 hours
p ( X < 725 ) = p (( X - μ )/ б √n < 725 - 750 / 55√25 )
= P ( Z > - 2.27 )
Hence P ( X < 725 ) = 0.0116 ( using Z-table )

A local business had various advertising campaigns. It had television ads numbered 1,2,3,4,5,6, newspaper and magazine ads numbered 1,2,3,4,5, and social media ads labeled 1,2. If a single advertisement campaign is picked at random, what is the probability that the advertisement is a social media ad AND has an odd number?
Provide the final answer as a fraction.
Answer:
1/2
Step-by-step explanation:
The probability that the advertisement is a social media ad and has an odd number is 1/13.
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, A local business had various advertising campaigns. It had television ads numbered 1,2,3,4,5,6, newspaper and magazine ads numbered 1,2,3,4,5, and social media ads labeled 1,2.
We need to find If a single advertisement campaign is picked at random, what is the probability that the advertisement is a social media ad AND has an odd number,
Probability = favorable outcomes / possible outcomes
Number of social media ads with an odd number = 1
Total number of ads = 13
We know that,
P(that the advertisement is a social media ad AND has an odd number)
= 1/13.
Hence, the probability that the advertisement is a social media ad and has an odd number is 1/13
