Mathematics
1 answer:
Dovator [93]3 years ago
6 0

Answer:

Parallelogram = 2 pairs of parallel sides and opposite angles are equal

Triangle BEA and triangle DFC are equivalent by side angle side

Therefore, angle DCF is equivalent to angle BAE

Angles FEB and DFE are right angles due to them being supplementary angles with angles BEA and DFC, respectively.

This means triangles BEC and DFA are equivalent.

This means angles FCB and EAD are equivalent, which means angles BCD and DAB are equivalent.

This also means angles ABC and ADC are equivalent.

Opposite angles equivalent = parallelogram

Step-by-step explanation:

The objective here is to Identify the level of measurement of the​ data, and explain what is wrong with the given calculation.

The data are at the <u> Nominal  </u>  level of measurement due to the fact that it portrays the qualitative levels of naming and representing different hierarchies  from 100 basketball, 200 basketball, 300 football, 400 anything else

b) We are being informed that, the average​ (mean) is calculated for 597 respondents and the result is 256.1.

Find two consecutive odd integers such that 32 more than the lesser is three times the greater​
Maslowich

Answer:

First odd number  = 13

Second odd number  = 15

Step-by-step explanation:

Let

First odd number  = 2x + 1

Second odd number = 2x + 3

According to given conditions:

32 + 2x + 1= 3 (2x + 3)

33 + 2x = 6x + 9

Taking terms with x to left and constants to right

2x - 6x = 9 - 33      (sign of transferred terms will be changed)

-4x = -24    

Dividing both sides by -4

x = -24/-4

x =6

So,

First odd number  = 2x + 1 =  2*6 + 1 = 12 + 1 =13

Second odd number = 2x + 3= 2*6 +3= 12 + 3 = 15

I hope it will help you!
