➷ Use this formula:
Sum of interior angles = (n - 2) x 180
'n' is the number of sides
Substitute in the value:
Sum of interior angles = (22 - 2) x 180
Solve:
Sum of interior angles = 3600

Answer:
k = 140 degrees.
The missing INTERIOR angle is 40 degrees.
Step-by-step explanation:
The missing interior angle would be 40.
Triangle angle sum theorem states the 3 interior angles of a triangle sum to 180.
64+76+40 = 180
The exterior angle theorem states the exterior angle of a triangle is equal to the sum of the two remote interior angles of the triangle.
Exterior angle k = 64+76
k= 140
Answer:
2760 ft^3
Step-by-step explanation:
<h2><u>volume of a cube formula:</u></h2>
Length * width* height
<h3><em><u>volume of the big cube</u></em></h3>
= 11*10*22
= 2420 ft^3
<h3><em><u>volume of the small cube</u></em></h3>
=7*4*10
=280 ft^3
<h3><em><u>now to find the total volume </u></em></h3>
= volume of the big cube + volume of the small cube
=2420 + 280
<u>=2760 ft^3 </u>
