You could use sin(25)=12/H
solve for H.
use pythagorean thm to doubke check answer
Answer:
<h2>V = 5 cm³</h2>
Step-by-step explanation:
The formula of a volume of a pyramid:
<em>B</em><em> - base area</em>
<em>H</em><em> - height</em>
<em />
In the base we have a square withe side <em>s = 2cm</em>
The formula of an area of a square with side <em>s</em>:
Substitute:
The height <em>H = 3.75 cm</em>.
Calculate the volume:
The photo is kinda blurry but can I have more background information about what’s going on here
<span>The formula fro the volume of a pyramid with a square base is:
Volume = L * L * H / 3
L * L * 9.6 / 3 = 147.97
L * L = (3 * 147.97) / 9.6
L * L = 46.24
Let's take the square root of both sides.
L = sqrt(46.24) = 6.8
The length of one edge of the square base is 6.8 units.</span>
Answer:
d = log 38/log31
d = 1.06
Step-by-step explanation:
31 ^ d = 38
Take log of both sides since the exponential equation have different base (always)
d log 31 = log 38
d = log 38 / log 31
d = 1.58 / 1.491
d = 1.06.
We can actually check to see if this is correct.
Substituting d = 1.06
31^ 1.06 = 38.092
(You see, that's approximately correct)
Keep learning, maths is fun!
