It has 18 triangles, as of my counting.
Answer:
9 ft
Step-by-step explanation:
So let's assume the shape is rectangular.
The perimeter of the rectangle with dimensions l and w is: 2w+2l.
We are given 48 feet of wood so we want 2w+2l=48.
Manny wants l to be 15 so insert this into equation: 2w+2(15)=48.
Now we need to solve
2w+2(15)=48
Multiplying 2 and 15:
2w+30=48
Subtract 30 on both sides:
2w =18
Divide both sides by 2:
w =9
We want the width to be 9 ft.
Answer:
The angles are 45°, 60° , 75°
Step-by-step explanation:
<h3>
Angle sum property:</h3>
Sum of all the angles of a triangle is 180°.
Equation:
3x + 5x + 4x = 180
Combine like terms,
12x = 180
x = 180/12

3x = 3 *15 = 45°
5x = 5* 15 = 75°
4x = 4 *15 = 60°
I Belive That There Can't Be 3 Numbers In A Rectangle Because At The Top You Get 24 And 6 And I Think It Is BxH One Half Times Base Times Height So 2xBxH .
