Answer:

Let me take 2,3,3 be 2x, 3x, 3x

Colin = 2x

Natasha = 3x

Angad = 3x

The equation forms to find out the value of x

2x + 3x + 3x = 48

=> 8x = 48

=> x = 48/8

=> x = 6

So share of Colin = 2x = £(2×6) = £12

Share of Natasha = 3x = £(3×6) = £18

share of Angad = 3x = £(3×6) = £18

For proof

£12 + £18 + £18 = £48

Answer:

$BC=12.8,\\AC=15.1$

Step-by-step explanation:

In right triangles only, the tangent of an angle is equal to its opposite side divided by its adjacent side.

Therefore, we have the following equation:

$\tan 58^{\circ}=\frac{BC}{8}$

Solving, we get:

$BC=8\tan 58^{\circ}\approx \boxed{12.8}$

Also in right triangles only, the cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle.

$\cos 58^{\circ}=\frac{8}{AC},\\AC=\frac{8}{\cos 58^{\circ}},\\AC\approx \boxed{15.1}$

We can also use the Pythagorean theorem now that we've found BC. However, if you choose to do so, make sure you don't use a rounded value for BC, as that could cause a notable deviation in your final answer.

Using the Pythagorean theorem to verify our answers:

$8^2+(8\tan 58^{\circ})^2=\left(\frac{8}{\cos 58^{\circ}}\right)^2\:\checkmark$

Answer:

The Cholula Pyramid has a bigger volume out of the two.

Step-by-step explanation:

The volume of a Pyramid is V=1/3Bh

Volume of the Choulula = 1/3 (2,178,576)(217)= 157,583,664

Volume of The Cheops Pyramid = 1/3 (570,025)(480)=91,204,000

157,583,664 is greater than 91,204,000
