Let’s solve for “a” and “s”.

a = 927 - 45s
a = 792 - 36s

927 - 45s = 792 - 36s
927 - 792 = 45s - 36s
135 = 9s
s = 15
a = 927 - (45 x 15) = 252

A continuación, se coloca el cociente que se obtenga (9) . Y luego el número obtenido (49) se multiplica por dicho cociente (9). Después, se resta (441) a la cantidad operable (492) del radicando.  El cociente obtenido (9) es la segunda cifra de la raíz, quedando (29) Bajamos el siguiente par de cifras y repetimos los pasos anteriores.

The vertex angle of an isosceles triangle measures 42°. A base angle in the triangle has a measure given by (2x + 3)°. What is t
larisa [96]

An isosceles triangle is one in which 2 angles have similar measure while the other one is different. In this case, the 2 vertex angles have a measure of 42 degrees, therefore the third angle which is equal to (2x + 3) is:

(2x + 3) + 42 + 42 = 180

2x + 3 = 96

<span>x = 46.5°</span>

Determine the equation of a circle with its centre at the origin in the Cartesian plane and with a radius of 2√3 units​
mojhsa [17]

Answer:

x^2 + y^2 = 12

Step-by-step explanation:

For a circle with the center at the origin [(h,k) is (0,0)]

use the formula:

x^2 + y^2 = r^2

In this case r is 2sqroot3.

(2sqroot3)^2 is 12.

2•2•sqrt3•sqrt3

= 4•3

= 12

So we get,

x^2 + y^2 = 12
