Answer:

d. 125, 216, 343

Step-by-step explanation:

The given sequence is 1, 8, 27, 64,.......

Now, we can write

1=1^3\\\\8=2^3\\\\27=3^3\\\\64=4^3

Here, we can see that the first term is cube of 1, second term is cube of 2, third term is cube of 3 and so on.

Therefore, in order to find the 5th, 6th and 7th term of the sequence, we have to take cube of 5, 6 and 7 respectively.

Therefore, the next three terms of the sequence are

5^3=125\\\\6^3=216\\\\7^3=729

The correct option is d which is 125, 216, 343

A. The two listed added up will be 180 degrees.

5x - 57 + 3x + 5 = 180

8x - 52 = 180

8x - 52 + 52 = 180 + 52

8x = 232

x = 29

B. The two listed added up will be 180 degrees.

2x + 4x + 150 = 180

6x + 150 = 180

6x + 150 - 150 = 180 - 150

6x = 30

x= 5
