Answer:

15 units

Step-by-step explanation:

ΔABC is right with ∠C = 90° and AB the hypotenuse

using Pythagoras' identity on the triangle

AB² = AC² + BC² , hence

BC² = AB² - AC² = 17² - 8² = 289 - 64 = 225

⇒BC = $\sqrt{225}$ = 15 units

What's the equation of this sequence 4,8,16,32,64,128,256

lions [1.4K]

Answer:

See below

Step-by-step explanation:

Here we have a function $a$ such that $a: \mathbb{N}\to \mathbb{R}$ and $a:n \mapsto a(n) = a_n$

The sequence is denoted as $\{a_n\}_{n\in\mathbb{N}}$ such that $\mathbb{N} = \{1, 2, 3, ...\}$

For this sequence, we would have

$\left\{ {2^n\right\}_{n = 2}^8$

But sure it seems to follow

$\left\{ {2^n\right\}_{n = 2}^\infty$

Answer: a=60, b= 50, c= 180-148=32, d=64, e=d=64, g=180-125=55 and since f=g then f=55, h= 76, I=h=76, j= 180-76= 104

Sorry I cannot explain why they are true because I only learn them in my language so I can’t explain them clearly in English but there is the answer

To find an angle measure, you would do inverse tan.

${ \tan }^{ - 1} (2.0874)$
You may need to hit the second button on your calculator to get this function.

Your answer turns up to be 64.402~~~~.

Rounded, the answer is 64 degrees.

Hope this helps!

Just divide $ 432 with $ 25, then you get 17.28, but there is no such thing as 0.28 week, so just round it up and the answer is 18 weeks
