Find the height in centimeters of a square pyramid with a volume of 455cm3 and a base edge length equal to the height. Give the

Ulleksa [173]

Answer:

$h = 7.69cm$

Step-by-step explanation:

Given

$Volume = 455cm^3$

$l = h$

Where:

$h \to height$

$l \to base\ length$

Required

The height

The volume is calculated as:

$Volume = l^2 * h$

This gives:

$Volume = h^2 * h$

$Volume = h^3$

Rewrite as:

$h^3 =Volume$

So, we have:

$h^3 = 455cm^3$

Take cube roots

$h = \sqrt[3]{455cm^3}$

$h = 7.69cm$ --- approximated

Answer:

(a) = 60

(b) = 70

Step-by-step explanation:

(a) Sum of all the angles of a triangle is 180

This is an equilateral Triangle

which means all the sides are equal since all the sides are equal that means all the angles are equal

$x + x + x = 180 \\ 3x = 180 \\ x = \frac{180}{3} \\ x = 60$

(b) this is an isosceles triangle with two equal sides that means the two opposite angles are equal

$40 + x + x = 180 \\ 40 + 2x = 180 \\ 2x = 180 - 40 \\ 2x = 140 \\ x = 70$
