skad [1K]

Answer:

$\boxed{\bold{ab+9a-6}}$

Step-by-step explanation:

Remove parenthesis: (a) = a

$\bold{2ab+9a-4-\left(ab+2\right)}$

$\bold{-\left(ab+2\right): \ -ab-2}$

Simplify $\bold{2ab+9a-4-ab-2}$

$\bold{ab+9a-6}$

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°

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

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

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

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

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

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

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

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