Use a special right triangle to find the value of y. Write as a decimal rounded to the nearest 10th

VladimirAG [237]

Given:

The figure of a right angle triangle.

To find:

The value of y.

Solution:

in a right angle triangle,

$\sin \theta=\dfrac{Opposite}{Hypotenuse}$

In the given right triangle,

$\sin 60^\circ=\dfrac{6}{y}$

$\dfrac{\sqrt{3}}{2}=\dfrac{6}{y}$

On cross multiplication, we get

$\sqrt{3}y=12$

$y=\dfrac{12}{\sqrt{3}}$

$y=\dfrac{12\sqrt{3}}{3}$

$y=4\sqrt{3}$

Therefore, the value of y is $4\sqrt{3}$ units.

Somebody please help me with my geometry

RSB [31]

Answer:

AB + BC = AC

BC = AC - AB

5x + 6 = 37 - (2 x + 3) = 37 -2 x - 3 = 34 - 2 x

7 x = 34 - 6 = 28

x = 4

BC = 5 x + 6 = 5 * 4 + 6 = 26

Check:

AB = 2 x + 3 = 2 * 4 + 3 = 11

AB + BC = 26 + 11 = 37

Find all real and complex zeros of p(x)=x^3-x^2-4x-6

yuradex [85]

Answer:

x = 3 , -1 + $\sqrt{-1}$ , -1 - $\sqrt{-1}$

Step-by-step explanation:

⇒ $p(x)=x^{3} -x^{2} -4x-6$

⇒ $p(x)=(x-3)(x^{2} +2x+2)$

now, for zeros of $(x^{2} +2x+2)$ ,

⇒ x = $\frac{-b}{2a}$ ± $\frac{\sqrt{b^{2}-4ac } }{2a}$

⇒ x = $\frac{-2}{2}$ ± $\frac{\sqrt{2^{2}-4(2) } }{2}$

⇒ x = -1 ± $\sqrt{-1}$

hence, all the roots are,

x = 3, -1 + $\sqrt{-1}$ , -1 - $\sqrt{-1}$
