Explain the difference between using the tangent ratio to solve for a missing angle in a right triangle versus using the cotange

Lena [83]

Answer:

While determining the angle $\theta$ with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other.

Step-by-step explanation:

See the diagram attached.

Let us assume a right triangle Δ ABC with ∠ B = 90°. Now, assume that the angle ∠ CAB = $\theta$ and the sides AB, BC, CA are 3, 4, 5 units respectively.

The tangent ratio of an angle $\theta$ is given by

$\tan \theta = \frac{BC}{AB} = \frac{4}{3}$

Again, the cotangent ratio of angle $\theta$ is given by

$\cot \theta = \frac{AB}{BC} = \frac{3}{4}$

Therefore, in both the cases of tangent ratio and cotangent ratio are inverse of each other and while determining the angle $\theta$ with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other. (Answer)

A stream is flowing down a slope into a larger river. The elevation of the head of the stream is 1,776 feet above sea level. The

ddd [48]

Answer:

-167.2 ft/mile

Step-by-step explanation:

The "rise" is 1298 -1776 = -478 ft. The run is given as 15,098 ft, so the slope is ...

slope = rise/run = -478/15098 ≈ -0.0316598

For 5280 feet in 1 mile, that rate of change amounts to ...

-0.0316598×5280 ft ≈ -167.2 ft . . . per mile
