ZJ and ZL are supplementary
ZJ and ZK are congruent.
65° K
ZJ and ZK are supplementary
ZI and ZL are congruent.

Answers

Answer:

J and K are supplementary

Step-by-step explanation:

Given

The attached image

Required

The true statement

From the attached image, it is hard to determine the values of angles I and L as there are no enough information to determine their values.

However, J and K can be worked easily.

From the image

J = 65^o --- vertically opposite angles

And:

K + 65^o = 180^o ---- angle on a straight line

Substitute: J = 65^o

K + J = 180^o

When two angles add up to 180, the angles are supplementary.

Hence, (c) is correct

Which fractions convert into repeating decimals? Select ALL that apply. 4/40. 12/100. 3/18. 1/5. 9/27​

Answers

9/27 & 3/18 are repeating decimals

Answer:

3/18     = 1.6666

9/27​    = 0.3333

Step-by-step explanation:

4/40    = 0.1

12/100 = 0.12

3/18     = 1.6666

1/5       = 0.2

9/27​    = 0.3333

Answer:

The answer is (1)/(30)\Big[2\log x-\log 6\Big]

Step-by-step explanation:

Given,

\int (x^(5)-x^(4))/(5x^(6)-6x^5)dx

=\int (x^4(x-1))/(x^5(5x-6))dx

=(1)/(6)\int\Big[(1)/(x)+(1)/(5x-6)\Big]dx

=\fracd{1}{6}\int (1)/(x)dx+(1)/(6* 5)\int(5)/(5x-6)dx

=(1)/(30)\Big[5\log x +\log (5x-6)\Big]

=(1)/(30)(2\log x-\log 6)

Hence the result.
