Answer:
θ = 38°
Step-by-step explanation:
The lower right triangle is congruent to the upper left triangle, so we have θ and 20° being the two acute angles in the triangle. The law of sines tells you ...
sin(θ)/9 = sin(20°)/5
sin(θ) = (9/5)sin(20°)
θ = arcsin(9/5·sin(20°)) ≈ 38°
___
Another solution to the triangle is θ = 180° -38° = 142°. The diagram clearly shows θ as an acute angle, so we take this second solution to be extraneous.
There is a correlation between height and speed of the serve
<h3>How to interpret the player statistics?</h3>
From the question, we understand that:
The taller a player, the faster the serve
This means that:
Height implies speed
In other words, there is correlation between the height and the speed of the service

Answer:
I have attached a picture of the completed graph.
The equation is k = r + 7
Kyle will be 59 when Ryan is 52.
Explanation:
Kyle's age is always seven years higher than Ryan's age.
Therefore, k (Kyle's age) = r (Ryan's age) + 7 (Number of years different)
If you move the negative on the left side of the second equation over to the right side, then we can see that the equation is equivalent to

.
Remember that an equation

represents a line with slope

and y-intercept

. Since both equations given have a slope of -2, but have different y-intercepts, they are
parallel.
