Answer:

Triangle

Step-by-step explanation:

A square pyramid has 4 sides that are triangles and a square base.

A plane that contains the vertex (top of the pyramid) and is perfectly vertical, must contain the vertex, the lines formed by the intersection of the plane with the left and right triangles, and the line formed by the intersection of the plane with the square. So the figure must be a triangle.

Answer:

105

For the 4 triangular faces, find the area with 1/2 × base × height = 1/2 × 5 × 8 = 20

4 triangles -> 20 × 4 = 80

The area of the square base is 25

80 + 25 - 105 $cm^{2}$

SIZIF [17.4K]

Answer:

7.75 cm

Step-by-step explanation:

Let a circle having centre O and AB is a tangent of the circle and OB is the radius of the circle = 2 cm. And join AO such that AO = 8 cm.

$AB=\sqrt{(AO)^{2}- (OB)^{2}} cm$

$AB=\sqrt {8^{2}-2^{2}}=\sqrt{60}=7.745966692 cm\approx 7.75 cm$

dedylja [7]

The midpoint of AB where $A(x_A;\ y_A)$ and $B(x_B;\ y_B)$

$\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)$

$A(-5;\ 13);\ B(-9;\ 21)$

The midpoint of AB: $\left(\dfrac{-5+(-9)}{2};\ \dfrac{13+21}{2}\right)=\left(\dfrac{-14}{2};\ \dfrac{34}{2}\right)=(-7;\ 17)$

Answer: A. (-7, 17)
