Answer:

11

Step-by-step explanation:

its something you basically have to just memorize and know... i dont know how to explain it, but like basically not all numbers have an even number square root. to have an even number for a square root, the number has to be able to be divided by the same 2 numbers. like 121, for it to have a whole number square root, it has to be able to be divided by 2 same numbers. or doubles... 11 times 11

11 squared is 121

square root of 121 is 11

hope this helps.

mark me brainliest :D

Answer:

11

Step-by-step explanation:

You can plug it inot a calculator, or can make a factor tree, in which the 2 factors would be 11, so 11^2=121 and $\sqrt121$ =11

Plz help<br>find the value of x

gayaneshka [121]

Answer:

$x^{\circ}=70^{\circ}$

Step-by-step explanation:

Lines MR and PQ are parallel. Continue the line MR up to the intersection with the line NQ. Denote the point of their intersection as A.

Consider triangle AMN. In this triangle,

$m\angle ANM=40^{\circ}$ - given;
$m\angle NMA=180^{\circ }-150^{\circ}=30^{\circ}$ - angles RMN and NMA are supplementary angles;

So, (as the sum of all interior angles add up to 180°)

$m\angle NAM=180^{\circ}-40^{\circ}-30^{\circ}=110^{\circ}$

Angles NAM and MAQ are supplementary angles, then

$m\angle MAQ = 180^{\circ}-110^{\circ}=70^{\circ}$

Angles MAQ and AQP are alternate interior angles, so they are congruant and

$x^{\circ}=70^{\circ}$
