its 9
Step-by-step explanation:
Answer:
A 161 square feet
Step-by-step explanation:
5×5=25
1/2 of 25 is 12.5(triangular face) ×2=25
5×8 is 40 (base and left face)
8×7 is 56 (right face)
25+40+40+56=161
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
6x - 3x + 1 = -2
3x = -3
x = -1
y = -3*-1 + 1
y = 3 + 1
y = 4
