Answer:

KPF = 9 and H = 129

Step-by-step explanation:

An inscribed quadrilateral in a circle has all diagonal angles add up to 180, so we can use this to find the angles of the quadrilateral.

H= 180-EPK and K = 180-E so H = 129 and K = 60

Now PF and EH are parallel, so PE is a transversal. That means FPE = 180 - E = 60. Now it's pretty easy to solve for KPF = FPE - EPK = 60 - 51 = 9.

Let me know if you don't see how I did any of this and I'll be happy to explain it..

taurus [48]

<h3>Write 6^8 • 6^7 as a single power:</h3>

$6^8 \times 6^7 = 6^{15}$

Solution:

Given that,

We have to write 6^8 • 6^7 as a single power

Given is:

$6^8 \times 6^7$

Use the following law of exponent

$a^m \times a^n = a^{m+n}$

When, the base is same, powers gets added

Therefore,

$6^8 \times 6^7 = 6^{8+7}\\\\6^8 \times 6^7 = 6^{15}$

Thus the given is written as a single power
