The answer is A 9.4 because you use the Pythagorean theorem to find the unknown side.
<h2><em>
The area of the pyramid net is 12 units</em></h2>
Step 1
Find the area of the Square in the middle
Formula for finding square:
Let's apply the formula and find our answer:
<em>The area of the square is 4 units</em>
<em></em>
Step 2
Find the area of all 4 triangles around the square
As you know, the formula for finding 1 triangle is as follows:
But, to find the area of 2 triangles, we can use this formula:
And to find 4 of them (with same dimensions;as required here), we can use this one:
Let's apply the formula then! What are we waiting for!!!!
<em></em>
<em>The area of ALL of the triangles around the square is 8 units</em>
<em></em>
Step 3
Add all areas to find FINAL ANSWER!
Easy!
4+8=12
<h2><em>
The area of the Pyramid Net is 12 units</em></h2>
Answer:
<em>y=</em><em>1</em><em>/</em><em>3</em><em> </em><em>would </em><em>be </em><em>the </em><em>correct</em><em> </em><em>answer</em><em> </em><em>as </em><em>long </em><em>as </em><em>the </em><em>x </em><em>is </em><em>not </em><em>only </em><em>attached</em><em> to</em><em> the</em><em> </em><em>three,</em><em> </em><em>but </em><em>1</em><em>/</em><em>3</em><em> </em><em>as </em><em>a </em><em>whole</em><em>.</em><em> </em><em>I </em><em>hope</em><em> </em><em>this </em><em>helps!</em>
Sum of all angles of a triangle = 180°
So,
angle E + angle O + angle C = 180°
=> 53° + 77° + C = 180°
=> 130° + angle C = 180°
=> angle C = 180° - 130°
=> angle C = 50°
Answer:
x < 8
Step-by-step explanation:
Add 4 to both sides
5x=40
Divide by 4
x < 8
