Answer:

A. 55°

Step-by-step explanation:

So the line goes through two angles, 125° and 55°

Lets check, does the angle look larger than 90°

Remember, 90° mean the line is perpendicular, or goes straight up.

I see that it is not. The angle that is less than 90° (55°) is correct.

If my answer is incorrect, pls correct me!

Input variable:<br>Output variable:

vovangra [49]

Answer:

A variable is an input variable if its Input property is Yes. Its value can be input from an external source, such as an Architect call flow. A variable whose Output property is Yes is an output variable.Since both properties can be set to yes, a variable can be both an input variable and an output variable.

X² - 6x + 4 = 0<br><br> solve and show work. ...?

ycow [4]

The answer is 3 + √5 and 3 - √5.

This is quadratic equation: x² - 6x + 4 = 0
The general quadratic equation is ax² + bx + c = 0
Our equation can be rewritten: 1x² + (-6)x + 4 = 0
So, in our equation we have: a = 1, b = -6, c = 4

Now, x can be calculated using the formula: $x_{1,2}= \frac{-b+/- \sqrt{ b^{2}-4ac } }{2a}$
$x_{1,2} =\frac{-(-6)+/- \sqrt{ (-6)^{2}-4*1*4 } }{2*1} = \frac{6+/- \sqrt{36-16} }{2} = \frac{6+/- \sqrt{20} }{2} =\frac{6+/- \sqrt{4*5} }{2}= \\ 
=\frac{6+/- \sqrt{4}* \sqrt{5} }{2} =\frac{2*3+/- 2\sqrt{5} }{2}= \frac{2(3+/- \sqrt{5}) }{2} =3+/- \sqrt{5}$

From here:
$x_{1} =3+ \sqrt{5} \\ 
x_{2} =3- \sqrt{5}$
