In ΔBCD, the measure of ∠D=90°, CB = 73, BD = 55, and DC = 48. What ratio represents the cosine of ∠C?
Answer: 48 over 73
Explanation: I had this exact question and didint know the asnwer and after I got it wrong the test gave me the answer
The ratio represents the cosine of ∠C 48 over 73.
What are angles?The sine of the complementary angle is referred to as the cosine of an angle. The given angle, which is 90 degrees at a right angle, is equivalent to the complementary angle. For instance, the complement of a 30° angle is a 60° angle.
Think of the right triangle ABC, where C is the right angle. Right triangle with standardized part labels. As previously said, we'll typically use the letters a, b, and c to represent the sides that are opposite of angles A, B, and C, respectively.
Angles A and B are complimentary because they add up to 90°, or since the total of the angles of a triangle is 180°, and angle C is 90°.
Therefore, The ratio represents the cosine of ∠C 48 over 73.

The Heisenberg uncertainty principle most directly applies to which of the
following types of matter?
Heisenberg uncertainty principle states that it is impossible to determine the exact position and the exact momentum of the particle simultaneously.
According to Heisenberg uncertainty principle, Δx.Δp≥ h/4π. Thus lesser the error in the momentum, more will be the error in the position of the particle.
Heisenberg uncertainty principle most directly applies position and momentum.
To answer the question, we need to know what Heinsenberg's uncertainty principle is.
What is Heinsenberg's uncertainty principle?Heisenberg's uncertainty principle states that for any particle, we cannot tell for a certainty both its postion, x and its momentum, p at the same time.
Now, Heisenberg's uncertainty principle is given mathematically as
Δx.Δp ≥ h/4π where
Δx = uncertainty in position, Δp = uncertainty in momentum and h = Planck's constantSo, we see in the relationship that we have both position and momentum.
So, Heisenberg uncertainty principle most directly applies position and momentum.
