Given:
S1 = 6 m
S2 = 8 m
S3 = 10 m
h = 3 m
Lateral Area Formula :
LA = hP ; height * perimeter
= 3m * (6 + 8 + 10)
= 3m * 24
LA = 72 m²
Surface Area Formula:
SA = 2B + hP : B = area of the base = ab / 2 = (6m * 8m)/2 = 48/2 = 24m²
SA = 2(24m²) + 72m²
SA = 48 m² + 72 m²
SA = 120 m²
This is an equilateral triangle, which means all the sides are the same length. So, the answer is 35. ☺♥
Hope this helps.
Solve for x
-53 + 8x = 3x + 47
8x - 3x = 47 + 53
5x = 100
x = 20
Answer:
<em>-4 4/5 deg F</em>
Step-by-step explanation:
3 pm: 5 1/5 deg
2 1/2 deg per hour for 4 hours = 2 1/2 deg * 4 = 10 deg
7 pm: 5 1/5 deg - 10 deg = -4 4/5 deg
