Answer:
A) 4.2
Step-by-step explanation:
A triangle-180 degrees. So angle Y is 180-90-65=25.
Using the law of Sines, 10/Sin90=x/Sin25
x=10Sin25/Sin90=4.2
Answer:
<h2>Width = 230 ft.</h2><h2 />
Step-by-step explanation:
perimeter of a rectangle (P) = 2L + 2W
where;
P = 1120 ft.
L = 100 + W
find: Width (W)
plugin values into the formula:
1120 = 2(100 + W) + 2W
1120 = 200 + 2W + 2W
1120 - 200 = 4W
W = 920 / 4
W = 230 ft.
proof:
P = 2(100 + 230) + 2(230)
1120 = 660 + 460
1120 = 1120 ---ok
Answer:
25/12
Step-by-step explanation:
1/2 + 2/5s = s - 3/4
2/5s = s - 5/4
-3/5s = -5/4
s = 25/12
