1350 cm²
para forrar la caja
Step-by-step explanation:
En un cubo cada una de las aristas que lo conforman miden lo mismo.
Un cubo tiene 6 caras.
La formula del área del área de las 6 caras del cubo es:
área total del cubo = a = 6*arista²
en este caso:
a = 6*(15cm)²
a = 6 * 225 cm²
a = 1350 cm²
You are dealing with a triangle and a rectangle, so just find the area of both of them then add it together.
To find the height of the triangle and the other side of the rectangle you have to use Trigonometry.
To find the height of the rectangle you must do:
8cos(30)= 6.928
Then solve for the length of the triangle by doing:
8Sin(30) = 4
Now just find the area of both shapes.
1/2(4* 6.928)+6.928*9=<span>76.2084064606</span>
Answer:

Step-by-step explanation:
Answer:
<h3>x = 7</h3>
Step-by-step explanation:
2 angles are added to result in = 180°
therefore
180 = 97 - 3x + 69 + 5x
180 = 166 + 2x
2x = 180 - 166
2x = 14
x = 14 ÷ 2
<h3>x = 7 ✅</h3>
The value of x = 7
