Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
To find:
The height of the building.
Solution:
We know that the heights of the objects and there shadows are always proportional.

Let x be the height of the building.

Multiply both sides by 139.




Therefore, the building is 75.8 feet long.
68 degrees because each quadrant of the shape is a right angle.
90 - 22 = 68 degrees
Less than 90°. All acute angles in a triangle are less than 90°.
Answer:
4.5 ft
Step-by-step explanation:
cos 68° = x / 12
x = 12 x cos 68° = 12 x 0.375 = 4.5 ft
