What’s a mean,median,and mode?

tamaranim1 [39]

The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. Mode is the number which appears most often in a set of numbers.

Hope this helps you :)

HELP!! What is the value of x??

nordsb [41]

Answer:

X = 41°

Step-by-step explanation:

<h3>Sum of interior Angles of a ∆ is 180°</h3>

$\angle1 + \angle2 + \angle3 = 180 \degree$

$Here \\ \angle1 = 105 \degree \\ \angle2 = ? \\ \angle3 = x$

$\angle4 = 146 \degree$

$here \: \angle2 + \angle4 = 180 \degree \\ \: (liner \: pair \: angle) degree\\ \angle2 + 146\degree = 180 \degree \\ \angle2 = 180 \degree - 146\degree \\ \angle2 = 34\degree$

$\angle1 + \angle2 + \angle3 = 180 \degree \\ 105\degree + 34\degree + x = 180\degree \\ 139\degree + x = 180\degree \\ x = 180\degree - 149\degree \\ x = 41\degree$
