What is the value of x enter your answer in the box x=

lions [1.4K]

Answer:

x = (3√34 + 1)/5 units

Step-by-step explanation:

Let's solve for x, using the Pythagorean theorem, this way:

BC is the Hypotenuse of the triangle ABC

BC² = 15² + 9²

BC² = 225 + 81

BC² = 306

BC = √9 * 34

BC = 3 √34

Now, we can substitute and solve for x, this way:

BC = 3x + 2x - 1

3 √34 = 3x + 2x - 1

3√ 34 + 1 = 5x

x = (3√34 + 1)/5 units

∆abc is isosceles, ab = bc, and ch is an altitude. how long is ac, if ch = 84 cm and m∠hbc = m∠bac +m∠bch?

Tems11 [23]

Given that ∆abc is isosceles and ab = bc, then m<bac = m<acb and m<hbc = 180 - m<bac - m<acb

Given that m∠hbc = m∠bac +m∠bch, then m<hbc + m<bch = m<bac + 2m<bch

But m<hbc + m<bch = 90°, thus 90° = m<bac + 2m<bch

Also, m∠bac + m∠ach = 90° ⇒ m<bac + 2m<bch = m<bac + m<ach ⇒ 2m<bch = m<ach

Since, Δabc is isosceles with ab = bc ⇒ m<bac = m<acb.

Also, m<acb = m<ach + m<bch ⇒ m<acb = 3m<bch = m<bac

Since m<bch : m<ach = 1 : 2 ⇒ bh : ah = 1 : 2

Thus, $bh:bc:ch=1:3:\sqrt{8}$

Given that ch = 84 cm, then

$\frac{bc}{ch} = \frac{bc}{84} = \frac{3}{\sqrt{8}} \\ \\ \Rightarrow bc= \frac{3\times84}{\sqrt{8}} =63\sqrt{2}=ab$

Now, $ah= \frac{2}{3} (63\sqrt{2})=42\sqrt{2}$

$ac= \sqrt{ch^2+ah^2} \\ \\ = \sqrt{84^2+(42\sqrt{2})^2} \\ \\ = \sqrt{7056+3528} = \sqrt{10584} \\ \\ =42\sqrt{6}$

Which pair represents the same complex number?

lorasvet [3.4K]

For this case we have the following complex number:
1 + i
Its equivalent pair is given by:
root (2) * (cos (pi / 4) + i * sin (pi / 4))
Rewriting we have:
root (2) * (root (2) / 2 + i * (root (2) / 2))
(2/2 + i * (2/2))
(1 + i)
Answer:
option A represents a pair with the same complex number
