Solve for an angle in right triangles

madreJ [45]

The angle of B is 56.2 degrees

<em><u>Solution:</u></em>

Given is a right angled triangle ABC

From given figure,

AB = 9

CB = 5

We have to find the angle of B

Let the angle of B be $\theta$

By definition of cosine,

$cos \theta = \frac{adjacent}{hypotenuse}$

Here, adjacent = CB and hypotenuse = AB

Therefore,

$cos \theta = \frac{5}{9}\\\\cos \theta = 0.556$

Taking cos inverse on both sides,

$\theta = cos^{-1}(0.556)\\\\\theta = 56.22038005 \approx 56.22$

Thus the angle of B is 56.22 degrees

X^2-5x-8=0 find the roots (zeros)

melomori [17]

Answer:

$x_1=\dfrac{5-\sqrt{57}}{2}\ ,\quad x_2=\dfrac{5+\sqrt{57}}{2}$

Step-by-step explanation:

$x^2-5x-8=0\\\\a=1\,,\ b=-5\,,\ c=-8\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\dfrac{-(-5)\pm\sqrt{(-5)^2-4\cdot1\cdot(-8)}}{2\cdot1}=\dfrac{5\pm\sqrt{25+32}}{2}=\dfrac{5\pm\sqrt{57}}{2}$
