BD bisects both the angles ABC and ADE

<u>Step-by-step explanation</u>:

IN ΔABD and ΔCBD ,

AD = CD [ given ]

BD = BD [ Common ]

AB = BC [ given ]

ΔABD ≅ ΔCBD [ SSS ]

∠ABD = ∠1

∠CBD = ∠2

∠1 =∠2 [ CPCT ] ( by using congruence theorem)

Also ,

∠3 = ∠4 [ CPCT ]

Hence, BD bisects both the angles ABC and ADE

Allushta [10]

Answer:

115 = 15 x + 40

the charge is $5 dollars per mile

Step-by-step explanation:

He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was 115

LEt x  be  the charge in dollars per hour

Initial charge is 40 and 15 miles travelled  in one day

total charge = 15x + 40

Given : total charge is 115

So the equation becomes

115 = 15 x + 40

Now we solve for x

Subtract 40 from both sides

75= 15 x

Divide both sides by 15

x= 5

so , the charge is $5 dollars per mile

N + N - 35000=833000
adell [148]

Answer:

N + 434000

Step-by-step explanation:

N + N - 35000 = 833000

(add 35000 to both sides)

N + N = 868000

(N + N is equivalent to 2N)

2N = 868000

(divide both sides by 2)

N = 434000

ddd [48]

Answer:

0.1187

Step-by-step explanation:

A = P (1 + k)^t

where A is the final amount,

P is the initial amount,

k is the monthly growth rate,

and t is the number of months.

70 = 50 (1 + k)^3

1.4 = (1 + k)^3

∛1.4 = 1 + k

k = -1 + ∛1.4

k = 0.1187
