Find the missing length

natka813 [3]

Answer:

x = 45

Step-by-step explanation:

Corresponding sides of similar triangles will be in same ratio.

$\dfrac{x}{x+18}=\dfrac{20}{28}$

Cross multiply

x*28 = 20*(x+18) {Use distributive method}

28x = 20x + 360

28x - 20x = 360

8x = 360

x = 360/8

x = 45

Answer:

c

Step-by-step explanation:

the formula is $\frac{y_{2}-y_{1} }{x_{2} -x_{1}}$

When we plug that in we get $\frac{-3-2}{6- (-4)} = \frac{-5}{10} = -\frac{1}{2}$

Hope this helps!
