You just need to plug those expressions inside the formula: it doesn't matter if they're expressions involving a variable instead of plain numbers: the formula becomes
If you want, you can simplify it by expanding the square and then multiply the two parenthesis:
Answer:
3 tiles will not fit together.
Step-by-step explanation:
Measure of an Interior angle of a polygon =
Here, n = number of sides of the polygon
Therefore, measure of the interior angles of a regular hexagon,
A =
A = 120°
Similarly, interior angle of the regular pentagon,
B =
B = 108°
Now m∠A + m∠B + m∠C = 360°
m∠C = 360° - (120° + 108°)
= 132°
To fit the given three tiles perfectly, interior angle (∠D) of the third Octagonal tile should be 132°.
D =
D = 135°
m∠C ≠ m∠D
Therefore, 3 tiles will not fit together.
Answer:
The surface area is
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces.
so
we have
substitute the values
