Answer:

C.Angle DAC is congruent to angle DAB

Step-by-step explanation:

We are given that

AC is congruent to segment AB.

We have to find the statement which is used to prove that angle ABD is congruent to angle ACD.

In triangle ABD and triangle ACD

AD\cong AD

Reflexive property of congruency

AC\cong AB (given)

\angle DAB\cong\angle DAC

\triangle ABD\cong \triangle ACD

(SAS Postulate)

\angle ABD\cong \angle ACD

(CPCT)

Hence, option C is true.

The length of a swimming pool is 10 ft shorter than twice the width. the length is 35 ft. what is the width
Hatshy [7]
Okay so we need to figure out the width of the swimming pool using the length, and we know the width is 10 ft shorter than twice the width. I believe the easiest way to do this would be to first do 35-10, and then divide it in half. That gives us 12.5. To check our work I'll do the problem 12.5+12.5+10=35.

The width of the swimming pool is 12.5 ft.

Please help will reward a lot of points and brainlest for the best answer
yawa3891 [41]
A is not right. Half the cookie would have an angle of 180
B is not right. 4 pieces would have an angle of 288
C is correct. 360/5 is 72 degrees
D is not right. 2 pieces would have an angle of 144
E is correct 90<144 so a 90 degree angle would fit in 2 pieces

I'd appreciate your guys' help! :)

Point slope form is :

8+12 = m(9-4)

8+12= 9m -4m

20= 5m

20/5= 5m/5

m= 4

Slope form

8= 4(9) +b

8= 36+b

-28=b

Y= 4x -28

Solve 732 H5 71z so what would x equal?
marin [14]
If the bases ar same, assume exponents are same

if
x^z=x^m
assume z=m

so
base is both 7 therefor
3x+5=1-x
solve
add x
4x+5=1
minus 5
4x=-4
divide 4
x=-1

Find the value of each variable
garri49 [273]
Triangles add to 180° and there is already 100° shown inside of the triangle (30° plus 70° = 100°). 180° -100° = 80°, which is x. X and y are vertical angles, so y is also 80°. The answer is B.
