Answer:
7
Step-by-step explanation:
the range is the difference between the smallest and largest numbers
It is 8 units.
2πr=16π
r=16π/2π
r=8.
The angle is in the second quadrant so only the sine is positive .
Length of the hypotenuse = sqrt (-1^2 + 3^2) = sqrt10
sine = 1/sqrt10 = 0.3162 to 4 dec places
tangent = 1 / -3 = -0.3333 to 4 d p's
cosine = -3/sqrt10 = -0.9487 to 4 d, p's.
Answer:
The similarity statement that expresses the relationship with the two triangles is that "Triangle P Q R is similar to Triangle W X Y"
Step-by-step explanation:
In drawing and labeling triangles, the three angles are labeled with letters that follow alphabetically. Thus, a triangle A B C should be in similarity with triangle x y z. Like wise from the above statements, triangle P R Q can only be similar in labeling in the range of W X Y even if the figures are not shown.
The true statement about right-angle triangle ABC is that: A. sin(A) = cos(C) and cos(A) = sin(C).
<h3>How to apply basic trigonometry?</h3>
In order to determine the angles, we would apply basic trigonometry. From the diagram of the right-angled triangle shown below, we can deduce the following parameters:
By applying the basic trigonometry functions, we have:
sin(A) = Opp/Hyp = a/c.
sin(C) = Opp/Hyp = c/b.
cos(A) = Adj/Hyp = c/b.
cos(C) = Adj/Hyp = a/c.
From the above, we can logically deduce that sin(A) is equal to cos(C) and cos(A) is equal to sin(C).
