Prove that tan 10+tan 70'+taniou = tanio tanfo'tam 1oo.

Galina-37 [17]

Question:

Prove that:

$tan(10) + tan(70) + tan(100) = tan(10). tan(70). tan(100)$

Answer:

Proved

Step-by-step explanation:

Given

$tan(10) + tan(70) + tan(100) = tan(10). tan(70). tan(100)$

Required

Prove

$tan(10) + tan(70) + tan(100) = tan(10). tan(70). tan(100)$

Subtract tan(10) from both sides

$- tan(10)+tan(10) + tan(70) + tan(100) = tan(10). tan(70). tan(100) - tan(10)$

$tan(70) + tan(100) = tan(10). tan(70). tan(100) - tan(10)$

Factorize the right hand size

$tan(70) + tan(100) = -tan(10)(-tan(70). tan(100) + 1)$

Rewrite as:

$tan(70) + tan(100) = -tan(10)(1-tan(70). tan(100))$

Divide both sides by $1-tan(70). tan(100)$

$\frac{tan(70) + tan(100)}{1-tan(70). tan(100)} = \frac{-tan(10)(1-tan(70). tan(100))}{1-tan(70). tan(100))}$

$\frac{tan(70) + tan(100)}{1-tan(70). tan(100)} = -tan(10)$

In trigonometry:

$tan(A + B) = \frac{tan(A) + tan(B)}{1 - tan(A)tan(B)}$

So:

$\frac{tan(70) + tan(100)}{1 - tan(70)tan(100)}$ can be expressed as: $tan(70 + 100)$

$\frac{tan(70) + tan(100)}{1-tan(70). tan(100)} = -tan(10)$ gives

$tan(70 + 100) = -tan(10)$

$tan(170) = -tan(10)$

In trigonometry:

$tan(180 - \theta) = -tan(\theta)$

So:

$tan(180 - 10) = -tan(10)$

Because RHS = LHS

Then:

$tan(10) + tan(70) + tan(100) = tan(10). tan(70). tan(100)$ has been proven

What is 15.375 rounded to the nearest hundredth?

MatroZZZ [7]

15.38. 7, the number in the hundredths place, is turned into 8 due to the following digit, 5. Since it is equal to the minimum, 5, the previous number is rounded up.

A store has apples on sale for $20.00 for 8 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $80.0

torisob [31]

Answer:

In $80.00 , we get 102 apples.

Step-by-step explanation:

As given, 8 pound apples costs = $20.00

so,

If we double the cost given , then we get double the times of apple given

⇒ we get 16 pound apple for = $40.00

Again, double the cost , gets double the apple

⇒ we get 32 pound apple for = $80.00

As,

1 pound= 16 ounces

⇒32 pound apple = 32×16 = 512 ounces

Now,

given that

1 apple = 5 ounces

⇒5 ounce = 1 apple

⇒1 ounce = $\frac{1}{5}$ apple

⇒512 ounces = $\frac{1}{5}$ ×512 = 102.4 ≈ 102 apples

∴ we get

In $80.00 , we get 102 apples.
