Find the value of x.

Lina20 [59]

Answer:

Hi,

Step-by-step explanation:

Using Al'Kashi theorem (law of cosines),

x²=26²+19²-2*26*19*cos(31°)

x²= 190,11870690...

$x=\sqrt{190.11870690} =13,7883540...\approx{13.8}$

I hope that this is not a control.

Anna, Irina, Avel, and Vlad are going on a road trip. The following table shows an incomplete probability model for who will be

Alex Ar [27]

Answer:

1. $\dfrac{3}{8}$

2. 240 km

Step-by-step explanation:

Anna drives $\dfrac{1}{8},$ Irina drives $\dfrac{3}{8},$ Vlad drives $\dfrac{1}{8},$ then Avel drives

$1-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8}{8}-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8-1-3-1}{8}=\dfrac{3}{8}.$

If the road trip involves 640 km of driving, then Avel drives

$640\cdot \dfrac{3}{8}=80\cdot 3=240\ km.$
