Answer:

True, they may not be congruent

Step-by-step explanation:

A figure cannot be determined as congruent from three angles alone. In order  for two shapes to be congruent, all corresponding parts must be congruent. This means all the sides and angles of the two shapes must be the same in order for the two shapes to be congruent. If we know all the angles are the same, the sides could still be different lengths, so this does not prove congruency.

Which equation represents this situation?
aalyn [17]

Answer:

dirk =13.25 hours

charlie =11 75 hours

Step-by-step explanation:

c+d=25------(1)

d-1.5=c-----(2)

from (1),

c+d=25

c=25-d-----(3)

substitude (3) into (2)

d-1.5=c

d-1.5=25-d

2d=26.5

d=13.25

if d=13.25 hours

c+d=25

c+13.25=25

c=25-13.25

c=11.75

neonofarm [45]

Given

Find out the  what was the insurance company's payment .  

To proof

As given

Sally Jones pays $50.00 a month for group health insurance

There is a $300 deductible

Her medical bills for the last year were $2,600.00

Linda's insurance company provided payment of 80% of the bills less the deductible.

Deductible

The  amount of money you will pay in an insurance claim before the insurance company starts paying you.

medical bill reducing the deductible = $2,600 -  $300

                                                             =  $2300

80 % is written in the decimal form

= \frac{80}{100}

= 0.8

than the equation becomes

Linda's insurance company provided payment  = 0.8× 2300

                                                                                = $1840

Therefore the the insurance company's payment be  $1840 .

Hence proved

The sum of three consecutive odd integers is − 87 . find the numbers.
DIA [1.3K]
Three consecutive odd integers are n, n+2 and n+4

n + n+2 + n+4 = -87
3n + 6 = -87
3n = -87 - 6
3n = -93
n = -93/3
n = -31

n+2 = -31 + 2 = -29
n+4 = -31 + 4 = -27

The numbers are -31, -29 and -27

What is the angle of rotation of this regular decagon? What is the measure of an interior angle?
SCORPION-xisa [38]
A decagon has 10 sides. If the polygon is symmetrical, the angle of rotation is given by the following equation:

360 / (number of sides)

Therefore, 

360 = 10 = 36.

The interior angles are determined by the following equation:

180 - (angle of rotation)

Therefore, 

180 - 36 = 144

The answer is A.
