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°

Sammy can roll a bowling ball at a rate of 5 miles in 30 seconds. How fast can he
IgorLugansk [536]

Answer:

600 mph

Step-by-step explanation:

Given that,

Distance covered by ball, d = 5 miles

Time taken, t = 30 seconds

1 second = (1/3600) hour

Speed = distance/time

v=\dfrac{5\ \text{miles}}{30\times \dfrac{1}{3600}\ \text{hour}}\\\\v=600\ mph

So, the speed of the ball is 600 mph.
