Answer:
other hooman is correct
Step-by-step explanation:
Total surface area of a triangular prism = width x height +(sum of sides + width) x length
475 = (width x 10) + (5 + 5 + width) x 15
475 = (10 x width) + (10 + width) x 15
475 = (10 x width) + 150 + (15 x width)
475 - 150 = 25 x width
325 = 25 x width
width = 325/25 = 13 feet
Answer:
36 cm
Step-by-step explanation:
Perimeter = sum of lenght of all sides
Perimeter = 6 + 10 + 8 + 12
Perimeter = 36 cm
Since it is the perimeter you add all the sides, so it is 5 1/2 + 5 1/2 * 6= 15, so the perimeter is 15:)
Answer:
40
Step-by-step explanation:
You know that the length of the lines are equal, therefore the value of the angles should also be equal.
Think of it this way:
The greater the angle, the greater the line and vice versa.
Hope this helps.
