Answer:
DE= 3.75 units
Step-by-step explanation:
Here we are given a right triangle Δ DEF right angled at E.
We are given that ∠EFD=49°
and DF = 55
DF is our hypotenuse .
Here we have to find the value of DE.
In order to do so , we will use trigonometric ratios
We know that
Perpendicular = DE
Hypotenuse = DF = 55
Degrees
We use trigonometric calculator and find sin 49° = 0.75
Hence we have
DE= 55*0.75
DE=41.509 units
The cotangent function is defined as the ratio between cosine and sine of a given angle, i.e.
Since you can't have zero at the denominator, the cotangent function is not defined when the sine is zero.
Let's look at your option:
, so the cotangent is defined here
, so the cotangent is not defined here
, so the cotangent is defined here
, so the cotangent is defined here
Answer:
Ratio of x-coordinates:
Ration of y-coordinates:
Step-by-step explanation:
The table is asking for the ratio of x-coordinates for each point (A, B, C and D) for both the image and pre-image. The ratio is the image 'x' or 'y' value ÷ the pre-image 'x' or 'y' value. Each ratio should be expressed in simplest form and should show the same pattern of dilation, or same scale factor. In this case, the second figure is 1/2 the size of the original figure.
Given :
Distance of bird from sea level, .
Distance between fish and sea level, .
To Find :
Distance between bird and fish.
Solution :
Distance between bird and fish is given by :
Therefore, distance between bird and fish is 8.958 feet.
Hence, this is the required solution.
