Answer:
How many plates are on the table as it results in only one value with no variability
Step-by-step explanation:
Suzie needs enough trim to cover the perimeter of the triangle. So she need enough to cover each side of 18. Thus 18 x 3 = 54 and 54 is your answer.
Answer:
<h3>AB ≈ 70m</h3>
Step-by-step explanation:
Check the attachment for the diagram.
You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;
tan 35° = opposite/adjacent
tan 35° = AB/BC
tan 35° = AB/100
AB = 100tan35°
AB = 100 * 0.7002
AB = 70.02m
Hence the distance across a lake between A and B is approximately 70m
