Answer:

2.1

Step-by-step explanation:

By the Law of Cosines,

a² = 5² + 6² - 2(5)(6)cos(20°)

a = sqrt(5² + 6² - 2(5)(6)cos(20°)), which is about 2.1

Answer:

Step-by-step explanation:

In this case each one is an independent event, therefore, the multiplication of each one would be the final probability

We have 5 Red Marbles, 4 Green Marbles, and 3 Blue Marbles, that is, there are 5 + 4 + 3 12 Marbles in total.

Now if I draw a red one, the probability would be: 5/12

When drawing another red, the probability would be: 4/11

When taking the green: 4/10

When removing the blue: 3/9

Finally, the final probability is:

P = (5/12) * (4/11) * (4/10) * (3/9)

P = 0.020

In other words, the probability of this happening is 2%

Answer:

$170$

Step-by-step explanation:

The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.

$wx = 2(42x + 1)$

We can add up that and the other arcs to 360.

$2(42x + 1) + 29x - 1 + 65x + 3$

$84x + 2 + 29x - 1 + 65x + 3 = 360$

$178x + 4 = 360$

$178x = 356$

$x = 2$

Plug in 2 for WX.

$84(2) + 2 = 170$
