The area of the base of the oblique pentagonal pyramid is 50 cm2 and the distance from the apex to the center of the pentagon is
kirza4 [7]

Answer:

\text{Height is }6\sqrt2cm

\text{The volume is }100\sqrt2cm^3    

Step-by-step explanation:

Given the area of the base of the oblique pentagonal pyramid is 50 cm^2 and the distance from the apex to the center of the pentagon is 6 cm. The measure of ∠ACB is 45°.

we know that

ABC is a right triangle

∠ACB=45°

AC=hypotenuse------> 6 cm

\sin 45^{\circ}=\frac{AB}{AC}

AB=AC\times \sin 45

AB=\frac{6}{\sqrt2}

AB=3\sqrt2

\text{Height is }6\sqrt2cm

Now, volume of pyramid

\text{Volume of the pyramid=}\frac{1}{3}\times \text{Area of the base}\times height

Area of the base=50 cm²

Height=6\sqrt2 cm

so, \text{volume of the pyramid=}\frac{1}{3}\times 50\times 6\sqrt2=100\sqrt2cm^3

\text{the volume is }100\sqrt2cm^3

A 6-foot tall man is standing in front of a school and notices his shadow measures 10 feet. At the same time, he notices the fla
irga5000 [103]

Answer:

The tall of the flag pole is 51 ft answer (A)

Step-by-step explanation:

∵ The tall of the man = 6 ft

∵ The his shadow = 10 ft

∵ The shadow of the flag pole = 85 ft

∵ Tall of the man/tall of the flag = shadow of the man/shadow

   of the flag

∴ 6/x = 10/85 ⇒ where x is the tall of the flag

∴ x = (6 × 85) ÷ 10 = 510 ÷ 10 = 51 ft

∴ The tall of the flag pole is 51 ft
