Answer:
He should buy lights that are 2088 inches long
Step-by-step explanation:
Craig has a rectangle wooden deck that measures 799 inches by 245 inches.
Let us say the length, L, is 799 inches and the breadth, B, is 245 inches.
He wants to put a string of lights around the deck.
This means that he needs to buy the length of lights that would be equal to the perimeter of the rectangular deck.
The perimeter of a rectangle is given as:
P = 2(L + B)
Hence, the length of lights he should buy is:
P = 2(799 + 245) = 2(1044)
P = 2088 inches
He should buy lights that are 2088 inches long.
Answer:
A = 7 x 9.3
A = 65.1 yd²
Step-by-step explanation:
<em>(I am assuming that either 7 or 9.3 refers to the height. It is unclear.)</em>
A = bh
Put the top point on the first point from the top and the other one on the first point from the bottom.
<span>Let </span>
<span>X= the altitude of the lighthouse above sea
level= 80 ft</span>
A = the angle of depression
Y= the distance of the boat from the lighthouse= 400 ft
tan A=X/Y------------------ >
80/400=0.2
arctan (0.2)=11.31 degree
The answer is the angle of depression is 11 degree
