Law of sines says: 
a / sin(A) = b / sin(B) = c / sin(C) 
where "a" is a leg of the triangle and "A" is its opposite angle. 
You are given an angle of 31 degrees with its opposite leg being a length of 17. 
You are then given an angle of 46 degrees and asked to find the length of its opposite side. 
So you can create the following equation: 
17 / sin(31) = a / sin(46) 
Using a calculator to get the value of the sins (I'll round them to 3 digits for now), we get: 
17 / 0.515 = a / 0.719 
Now solve for a 
17(0.719) = 0.515a 12.223 = 0.515a 12.223 / 0.515 = a a = 23.734 
So rounded to tenths of a unit, a = 23.7

mart [117]

The required probability for three numbers rolled on the dice are the sides of a triangle is 31/36.

<h3>What is probability?</h3>

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability.

Here,

When three dice are rolled, there are 63=216 possible outcomes, or triplets (x, y, z).

Once more, in a triangle, any two sides added together are larger than the third side, or (x+y)>z.

As a result, 186 outcomes or triplets are possible and satisfy this property.

Hence, the required probability is 186/216=31/36.

The required probability is 31/36 for three dice rolls to produce triangle sides.

1. What is the slope of a line parallel to -8x + y = 2?
kotegsom [21]

Answer:

slope of the parallel line = 8

Step-by-step explanation:

Parallel lines have the same slope. To determine the equation of the other line, you need to transform the given linear equation into its slope-intercept form, y = mx + b:

-8x + y = 2

Add 8x to both sides to isolate y:

-8x + 8x + y = 8x + 2

y = 8x + 2 (this is the slope-intercept form where the slope (m) = 8, and the y-intercept (b) = 2).

Given that the slope of the first equation is 8, then we can assume that the slope of line parallel to -8x + y = 2 will also be 8.

Juliette won her 400m race in a time of 1:01.71. If she ran the 1500m at the same rate,
slamgirl [31]

Answer:

230.77 seconds or about 3.85 minutes (2 minutes 50.4 seconds)

Step-by-step explanation:

First I will convert the minutes into seconds to make this a little easier.

1:01.71 would just be 61.71 seconds

400/61.71 is her speed for the first race. (speed is distance/time)

That is approximately 6.5 meters per second

time is distance/speed

1500/6.5= 230.769...

I do not know what you need to round to, but Juliette would take 230.769 seconds to run the 1500 meter race.
