Si "m" es el lado mayor de un triángulo, dos cuyos ángulos interiores miden 30° y 60°, entonces el perímetro del triángulo es

lions [1.4K]

Answer:

$perimetro = \dfrac{(3 + \sqrt{3})m}{2}$

Step-by-step explanation:

triángulo 30°-60°-90°

$1~:~\sqrt{3}~:~2$

$1m~:~m\sqrt{3}~:~2m$

$\dfrac{m}{2}~:~\dfrac{m\sqrt{3}}{2}~:~m$

$perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + m$

$perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + \dfrac{2m}{2}$

$perimetro = \dfrac{m + m\sqrt{3} + 2m}{2}$

$perimetro = \dfrac{3m + m\sqrt{3}}{2}$

$perimetro = \dfrac{(3 + \sqrt{3})m}{2}$

mart [117]

Answer:

The shaded area is $23\ in^{2}$

Step-by-step explanation:

we know that

The shaded area is equal to the area of the large square minus the area of the two smaller squares

$A=6^{2} -(3^{2} +2^{2})\\ \\ A=(2*3)^{2} -(3^{2} +2^{2})\\ \\A=(2^{2})(3^{2}) -(3^{2} +2^{2})$

Calculate the shaded area

Remember that

$3^{2}=9\\ 2^{2}=4$

substitute

$A=(4)(9) -(9 +4)\\ \\A=36-13\\ \\A=23\ in^{2}$
