Answer:

4 $m^{2}$ $k^{2}$ ;28 $k^{2}$ ;8 km

9m $m^{2}$ k;63mk; 18 $m^{2}$

Step-by-step explanation:

4k· $m^{2}$ k=4 $m^{2}$ $k^{2}$

4k·7k=28 $k^{2}$

4k·2m=8km

9m· $m^{2}$ k=9m $m^{2}$ k

9m·7k=63mk

9m·2m=18 $m^{2}$

Se multiplican los números y luego las letras

Si se multiplican dos letras iguales lo elevamos al cuadrado

EJEMPLO:m· m= $m^{2}$

"Find the tangent ratio of angle Θ. <br><br> "

PSYCHO15rus [73]

Tangent Θ = opposite / adjacent

AB = short leg = opposite = 12
AC = long leg = adjacent = 5
BC = hypotenuse = 13

tangent Θ = 12/5 ⇒⇒⇒ this is in ratio form
tanΘ = 2.4 ⇒⇒⇒ this is in decimal form

given the information in this picture which trigonomic identity can be used to solve for the height of the blue ladder that is l

professor190 [17]

Perpendicular=50ft=P
Hypotenuse=h=?

$\\ \tt\hookrightarrow sin\theta=\dfrac{P}{H}$

$\\ \tt\hookrightarrow sin47=\dfrac{50}{h}$

$\\ \tt\hookrightarrow h=\dfrac{50}{sin47}$

$\\ \tt\hookrightarrow h=\dfrac{50}{0.73}$

$\\ \tt\hookrightarrow h=68.4ft$

HELP ME!! SOMEBODY PLEASE HELP ME

IRISSAK [1]

6^2 = x (x - 9)
x^2 - 9x - 36 = 0
(x -12)(x + 3) = 0
x - 12 = 0; x = 12
x +3 = 0; x = -3

so in this case x = 12 then DC = 12 - 9 = 3

y^2 = 12^2 - 6^2
y^2 = 144 - 36
y^2 = 108
y = 10.4
