Given:
Length of the ladder = 20 ft
Distance between base of the ladder and wall = 4 ft
To find:
The angle measure of the ladder to the ground to the nearest degree.
Solution:
Ladder is the hypotenuse of a right triangle. Here, we have,
Hypotenuse = 20 ft
Base = 4 ft
In a right angle triangle,
Taking cos inverse on both sides, we get
Therefore, the correct option is A.
Answer:
by adding a transverse line to it interesting both of them
Answer:this is the answer

Two 12-Hour Periods The 12-hour system divides the 24 hours of a day into two periods lasting 12 hours each. The first 12-hour period is designated as am. It runs from midnight to noon. The second period, marked pm, covers the 12 hours from noon to midnight.
Squares are:
1. Equal on all 4 sides
2. All Have the same angle measure of 90 degrees
