Step-by-step explanation:

<u>We have ordered pairs:</u>

  • (1, 32), (2, 26), (3, 20), (4, 14), (5, 8)

<u>Looking at the sequence of y-values:</u>

  • 32, 26, 20, 14, 8

We see it is the arithmetic progression with common difference of -6.

It means the function representing this relationship is linear.

Two Identical Buildings stand parallel on opposite sides of a road. Find the angle of depression from A to B
Aleks04 [339]

Answer:

8.7°

Step-by-step explanation:

The above problem can be represented by a right angled triangle with height of 7 m, hypotenuse = AB.

The base of the triangle is gotten by finding the diagonal of the road. That is using Pythagoras theorem:

base² = 43² + 15²

base² = 2074

base = 45.54 m

Using trigonometric function to find angle A:

tan(A) = base / height

tan(A) = 45.54 / 7

tan(A) = 6.506

A = tan⁻¹ (6.506)

A = 81.3°

Angle of depression = 90° - A = 90 - 81.3

Angle of depression = = 8.7°
