Answer:
The base of the ladder is 2.58 m.
Step-by-step explanation:
Given that,
The angle of elevation for a ladder from the ground is 75°.
The length of a ladder, H = 10 foot
We need to find the distance from the house should you place the base of the latter. Let the base of the ladder is b. Using trigonometry,

So, the base of the ladder is 2.58 m.
Answer:
what the hecker is that.
okay so your simplifying it, 12? i think.
Answer:
22 sides
Step-by-step explanation:
The expression to find an interior angle of a polygon is:

The expression to find an exterior angle of a polygon is:

Please note that "n" represents the number of sides the polygon has.
We can use these two expressions to set up an equation.

Multiply both sides by "n":

Now, distribute:

Divide both sides by 10:


Add 36 to both sides:

Divide both sides by 18:

The polygon has 22 sides
