Find the length of the side of a square with an area of 25

Alexxx [7]

Area squares is the side*side, or
$x^{2} =25$
$\sqrt{ x^{2} } = \sqrt{25}$
$x=5$

So, each side equals 5.

Answer:

C. 21°

Step-by-step explanation:

In triangle ABC, perpendiculars dropped on the sides AB and AC from the ray BD are equal in measure or congruent.

Therefore, ray BD is equidistant from the sides AB and AC.

So, ray BD will be the bisector of angle ABC.

$\therefore m\angle ABD = m\angle DBC$

(Angle bisector theorem)

$\therefore (3x+9)\degree = (45-6x)\degree$

$\therefore 3x+9 = 45-6x$

$\therefore 3x+6x = 45-9$

$\therefore 9x = 36$

$\therefore x =\frac{36}{9}$

$\therefore x =4$

$\therefore (3x+9)\degree = (3*4+9)\degree=(12+9)\degree =21\degree$

$\implies m\angle ABD=21\degree$

Which expression is equivalent to ^4 sqrt 144a^12 b^3

Alex_Xolod [135]

The expression equivalent to ^4 sqrt 144a^12 b^3 will be found by simplifying our expression as follows:
 ^4 sqrt 144a^12 b^3
=(144a^12b^3)^(1/4)
=(12^2a^12b^3)^(1/4)
=12^(1/4*2)a^(12*1/4)b^(3*1/4)
=12^(1/2)a^3b^(3/4)

Answer: 12^(1/2)a^3b^(3/4)
