Given: PKHE - inscribed, m∠E=120°<br> m∠EPK=51°, PF ∥EH<br> Find: m∠KPF, m∠H.
3241004551 [841]

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..

\huge{ \mathbf{  \underline{ Answer }\:  \:  ✓ }}

The sand we need to fill the cylinders is equal to the total volume of the six cylindrical posts .

Given terms ( common for each cylinder ) :

  • height (h) = 4 ft
  • radius. (r) = 0.5 ft

\large \boxed{ \mathrm{volume =\pi {r}^{2}  h}}

  • 3.14 \times  \dfrac{1}{2}  \times   \dfrac{1}{2}  \times 4

  • \mathrm{3.14 \: ft {}^{3} }

Since volume of each cylinder is equal, so total volume of six cylindrical post :

  • 3.14 \times 6

  • { \mathrm{18.84 \: ft {}^{3} }}
