Answer:
10.2cm
Step-by-step explanation:
Perimeter is the sum of the lengths of all sides.
1st side: 9cm
2nd side: 7.8cm
Perimeter: 27cm
Perimeter = 1st + 2nd +3rd side of a triangle
27cm = 9cm +7.8cm + 3rd side
3rd side = 27cm - 9cm -7.8cm
= 10.2cm
Answer:
Step-by-step explanation:
<u>According to the question we have:</u>
- Formula h = - 16t + s
- h = 0
- s = 555.427 ft
- t = ?
<u>Substitute the given values and solve for t:</u>
- 0 = - 16t + 555.427
- 16t = 555.427
- t = 555.427/16
- t = 34.714
